Video Transcript for Dutton-Lainson Boat Trailer Parts - Roller and Bunk Parts - DL21755 Review
Today were going to review part number DL21755. This is the Dutton-Lainson Boat Trailer Standard Roller Bunk in five foot long sections. These Dutton-Lainson Roller Bunks will provide a quick, easy and inexpensive way to upgrade your bunk-style trailers to rollers. They feature a non-marking two-compound roller which has a durable wear-resistant inner surface and a soft boat cushioning outer surface. These roller bunks are designed to attach directly to your wooden bunks that are two inches wide on your boat trailer. Basically, you would set this on to your wooden bunk and there are holes right here, pre-drilled that you would just mark and then drill a hole through and then use a bolt to attach it to the wooden bunk.
Now if your boat trailer does not have wooden bunks or you want to remove the wooden bunks, you can still use these. What you have to do is use this roller bunk bracket which is sold separately. Its part number DL21762 and you will need at least two of these for each section. And what these would do is where the bolts would normally go through the wooden bunk, you would just put the section that has the hook part on it right in the hole and then the bolt would gone through here and then with this bracket having the slotted holes, you can adjust it and bolt it to your boat trailer and get the correct height you need. This part is constructed of a 14-gauge steel, has a black powdered-coat finish, has a total weight capacity for both of these roller bunks is 3000 pounds maximum and again they are five feet long and they are two inches wide.
The rollers on them are free to pivot and they will align with the boat hull. Each five foot section will have six sets of two rollers so 12 rollers on five foot section and 12 on another one. So over all for both roller bunks, you would have 12 sets of two rollers. This part is made in the USA. That should do it on a review on part number DL21755.

The paint peeled off the steel in months and when I called customer service they wouldn’t stand behind the product. They said they’re not intended to be in water. Seems a poor choice of materials for Boat trailer rollers that are produced to roll your boat into the water??

Worked great for loading a raft onto our trailer
by: ClassicCity06/21/2023
These boat trailer roller bunks worked absolutely perfectly on my jet ski trailer. Very durable, professionally made. Easy to install. Fit like a glove without having to remove the carpet padding on the rails. This company knows what they are doing and for a very reasonable price. A year later and they are still working like I got them yesterday.
by: Joel 01/22/2024
Excellent product, heavy duty, easy to install, and so far have worked flawlessly for me, great product!

I bought these hoping I could adapt them as rollers on a floating jetski dock. Took a little ingenuity, but worked like a champ. I can now push my ski off the dock with one hand! Great product.
by: Big O HRL07/09/2016
I had carpeted bunks on my trailer and always had problems launching my boat due to the dry carpet, I couldn't always submerge the bunks in the water due to the tide. I decided to try the rollers and Wow, what a difference it makes. Easy Off, and On. I have a flat bottom Scooter and I recommend the rollers for easy launching. The materials used are of good quality and the wheels do not mar the fiberglass bottom. Just be sure keep the boat secured until reaching the water because it will roll off, it's that easy to get the boat off the trailer. Thank you Etrailer, you have a good product.

The roller bunks are still working however the metal frames are rusting very badly after 1 yr. If you can make these in galvanized metal you will really have a winner. Ill keep checking back to look for them.
by: Wayne B09/15/2014
We considered several alternatives for a way to easily move our 15' sailboat out of the water, over our bulkhead and across our dock. The DL21755 roller bunks work perfectly. I can almost move the boat across the dock with one hand. We mounted them on 2x2's that we attached to the dock. We used 2x2's to keep a low profile.
High quality product and the service and prices from etrailer were absolutely fabulous. Rollers arrived in a few days and were packed very securely. We will be doing business again with etrailer!
Thank you

Outstanding customer service!
by: Matt 05/29/2021
Terrific product - But be careful at the ramp! Don't release the winch strap from the boat if the ramp is on a slight incline because the rearward weight of the motor will cause the boat to just fly off the trailer into the water. It happened to me the first time I used it since the installation. It was on a river and the boat started to drift away. Lucky for me a local rescue team was there doing some practice and they retrieved the boat for me. Now I attach a spring shackle, with 1/4" rope attached, to the boat clevis before removing the winch hook. I can gently let the boat slide off the trailer and keep it under control with the rope.
I'm 77 and it was getting harder for me to push the boat off of the trailer if the river was low and equally hard to pull it back onto the trailer at the end of the day. Now it is so simple! I just push the boat out into the flow and when it gets to the center of the trailer I just pull up on the rope and center the bottom of the boat over the bunks. The boat easily comes almost all the way up to the rubber "V" bumper on the trailer. Then it is a simple matter to crank the winch and bring the boat up tight against the bumper.

Excellent! They look like they will be helpful in launching my boat on a trailer. I could not do so with my current trailer. I think the parts sent will modify my trailer into a useful device. Thank you.

They worked great...but i have sold that boat and trailer since then. I may be interested in getting some wheel bunks for my latest boat.
by: Tommy04/24/2018
Works great seems to hold up very well for sitting in fresh water for a year straight. I could not get my wave runner or jet Jon out of the water without them. Great product for a home made ski lift.

Still working great
by: David06/15/2021
First off I would like to say that I experienced great customer service throughout my recent orders. I knew that some of my products where back ordered, but I was willing to wait for some of them, others they were able to give me suggestions for in stock items and it worked out perfect. As far as this product goes (which I waited for), I greatly dislike giving reviews right after I receive a product and don't have time to see how it will hold up, but this roller bunker installed very easy and once adjusted worked very well. My old roller bunker started to loose it's wheels (many years old). I only wish I was better prepared, in my head I though I was going to lag screw these in from the top (into the wooden bunker) but after I got the boat off I realized they bolted through the wooden bunker, so I quickly ran down the road and got stainless 3/8 x 2.5" bolts, after that it was quick. If they don't last I will make sure to update my review.

GREAT SO EASY TO LOAD AND UNLOAD
by: David S.11/05/2014
The rails and rollers are a great product and arrived on time. The Bunk Style Guides do not have mounting brackets suitable for mounting on a standard boat trailer from Academy which uses Angle Stock aluminum for their frame. The brackets are only useable on square or rectangular frames. I fabricated my on mounting hardware to install them.
by: larry s.07/12/2016
I as of yet not installed my rollers, only because of finding the time to do it. I was however very pleased of the fast delivery. As I inspected the product, I was impressed of the quality of assembly. From what I can tell, I will be quite pleased with the end result.

they do fine, but not as well as I had hoped

The rollers exceed expectations. The delivery was quick and without incident. Very satisfied customer
by: Isaac S.08/23/2015
The rollers are great, BUT it's possible they won't fit over existing wood bunks & brackets. I have a load rite bandit trailer and ran into this issue. The resolution was to remove the wood bunks and brackets / install with new brackets, so figure the additional cost when purchasing.
by: Jay L.08/13/2017
the roller bunk works well. i had to remove the old bunks (were carpeted 2X4 laying flat) and make new rails the width of the roller bunk channel. i couldn't use the old trailer hardware so i had to improvise. tested new setup this past weekend and they worked very well.
by: Tim06/27/2017
I used four roller bunks to build a jet ski ramp off of a fresh water seawall. The ramp is partially underwater 6 months a year. The bunks did the job and have held up very well in the first year.

modified a utility trailer to haul a 15'6" canoe no problem with a couple of keel rollers now it's a easy one-man load and unload good quality parts at great price!

by: Roger03/18/2013
This product is very important to me. At 70 years old, loading and unloading my boat by myself can be a chore.
Also, the lakes I fish sometimes have low water levels with unpaved ramps and again roller bunks makes loading and unloading easier.
This product is a godsend!
by: Tom V.03/30/2015
Great product but even greater customer service.
I ordered a set of these and then realized that I needed to also order a trailer coupler. I was pleasantly surprised to be able to call etrailer on a SUNDAY and find a knowledgeable LIVE body to talk to. I successfully revised my order and received all my items 3 days later!
Great customer service.
by: Johnny G11/29/2020
these bunk rollers are a preferred way of allowing your boat to roll on the trailer along with keel rollers instead of a float on. This product is a must for your boat trailer. The one thing I would like to see is that the frame be available in hot dipped galvanized for salt water use.

- Dutton-Lainson Boat Trailer Standard Roller Bunks for Hauling Heavy Loads of SeaweedThanks for the great picture! Sorry to hear you're having problem with the 1,500 lbs CE Smith Roller Bunks Item # CE27710. It sounds like they are overload so let's get you upgraded to the Dutton-Lainson Boat Trailer Standard Roller Bunks item # DL21755. These roller bunks are 5' Long but have a 3,000 lbs capacity per pair so you'll need 4 sets to make sure these are not overloaded as well. The zinc-plated steel rollers are constructed of 12-gauge, galvanized steel.

- Will Using Roller Bunks Make Launching and Loading a Saturn SD430 Boat EasierRoller bunks are definitely going to make launching and loading the boat much easier. having carpeted bunks on the trailer now will not be an issue. You can use roller bunk, # DL21741, that can be mounted flat against the bunks. The mounting holes are on the flat bottom of the frame on the rollers so these bunks are more versatile. They have a capacity of 3,000 pounds.
view full answer... - Can Roller Bunks be Used as Tilting BunksThe mounting brackets that you mentioned, # DL21762, can also tilt but the part that attaches to the trailer will be fixed. If by tilting you mean front to back (up and down) then roller bunks # DL21755 are not really designed to work that way. You may be able to attach bunks # DL21741 directly to the wooden bunks that you have and keep the tilting feature the same. You may have to position the bunks a little differently since this method essentially makes the bunks taller by about 2...
view full answer... - Weight Capacity of Dutton-Lainson Standard Roller Bunks DL21755The Dutton-Lainson Standard Roller Bunks # DL21755 have a maximum load capacity of 3000-lbs per set so they will able to handle your 2500-lb Triton bass boat. These can mount directly on 2 x 4 boards using hardware you supply; stainless or galvanized hardware is recommended for corrosion resistance. Part # DL21755 consists of a set of two rollers, each with 6 sets of wheels. You may want to use two sets, to give you 10-feet of roller surface to better support each side of the hull.
view full answer... - Roller Bunks For a 8,000LB to 10,000LB 25' BoatThe Rollers # DL21755 and # DL21741 are our highest capacity rollers at 3,000lbs capacity per set. As each set is 5' long you can disperse the weight of your 25' boat across multiple sets of rollers to achieve the 8,000-10,000lb capacity you are needing.
view full answer... - Will Storing a PWC on Rollers for a Long Period of Time Damage the HullFor PWC you can store them on roller bunks. For boats they do not recommend storing on rollers for a long period of time unless wood blocks are used. Otherwise small indentations or cracks can occur on the hull.
view full answer... - Using Roller Bunks for PWC Ramp & TrailerRoller bunks like the 5-foot Dutton-Lainson # DL21755 and the other similar products shown on the linked page will work best when they are positioned on the trailer or ramp surface in such a way that allows the maximum contact between the watercraft's hull and the flat top surface of the rollers. The fuller and more even the contact the easier the rolling action will be. On a PWC the hull can have many different profiles or shapes. These can include the common V and modified V, and the...

You place a bolt through these holes. The hook part of the bracket, # DL21762, goes around the the bolt underneath the rollers. The slotted portion of the bracket is then bolted to the trailer or existing wooden bunks. The holes are slotted so it can be adjusted higher or lower on the bolts. The roller bunk brackets, # DL21762, are sold in quantities of 1 but a total of 4 are needed to mount a pair of...

And it worked out great. Take a look at the pictures I have included. The key is to have enough rollers for the length of the ramp and to support the weight. The roller bunk sets are rated for a maximum of 3,000 pounds. There are 2 bunks in a set, 5 feet long each. You can get them from us and the current pricing is available on the product page.

- Will Dutton-Lainson Boat Trailer Standard Roller Bunk # DL21755 Handle 3000-lb Sea Ray 190According to the Sea Ray website (which has an excellent archive section with complete specs) your 1997 model year 190 Bowrider has a dry weight of 2750-lbs. Since the boat's entire weight will never be concentrated in one spot you will have no problem using the Dutton-Lainson Boat Trailer Standard Roller Bunk # DL21755. You can also use multiple sets if you want to. The roller bunks are sold without hardware or mounting brackets; we offer bracket # DL21762 and four are needed for each...
view full answer... - Bunk Roller and Bracket Recommendations for a Trailer Attaching to Side Rails of TrailerI believe your best solution would be to get Roller Bunks part # DL21740 and then use Roller Bunk Brackets # DL21742. The way these brackets install on the trailer and install to the brackets allows the brackets to install on cross rails or side rails. The roller bunks # DL21755 that you referenced would not be ideal for you they are set up to install onto cross rails.
view full answer... - Advisability of Leaving Bunks Loose When Installing Bunk Rollers on Boat TrailerIn order to provide a solid rest for the boat and to hold it securely, I wouldn't recommend leaving the fasteners loose so that the bunks can swivel. You can loosen the fasteners in order to make adjustments so that the rollers are perpendicular to the bottom of the boat, but you'll want to tighten everything up once it's adjusted correctly. You might consider using Roller Guide-Ons like part # CE27610. The guide-ons would allow you to align the boat correctly when you're loading it on...
view full answer... - Galvanized Roller Bunks for 23 ft Boston Whaler Conquest on EZ Loader TrailerBunk rollers like the # DL21755 model would be a good addition to your trailer, and would make launching and retrieving your boat easier. The rollers would cause less friction between the boat and the bunks, therefore requiring considerably less effort to winch the boat up onto the trailer. For a comparable galvanized product, I would recommend part # DL21741, with each 5 foot section having a 3000 lb capacity per pair of rollers. These rollers can be fastened directly to the edge of your...
view full answer... - Recommendations for Bunk Rollers for Jet-Ski TrailerBunk rollers like the # DL21754 you mentioned would be an excellent choice for PWC's that rest on the edges of the bunks, as most of them do. At 4 foot long, they'd probably offer plenty of support, but I'd recommend getting a set that's close in length to your existing bunk boards. A 5 foot long set is also available as part # DL21755. The rollers would simply mount right over the edge of your existing bunk boards, but you'll probably need to remove the carpet from them first. The rollers...

view full answer... - Roller Bunk Recommendation for a 17 Foot Ranger Jet Boat and King Salt Water Boat TrailerThe easiest solution, if possible, is to back the trailer further into the water. If that is not an option, rollers could help you and definitely make it easier to launch the boat and pull it back on the trailer. For rollers, given that your bunks are flat and about 8 feet long, I would go with 2 sets of # DL21740. Each piece is 4 feet long and they can be mounted directly to the bunks. Each set of rollers has a 2,500 pound capacity.

They recommend that you use 2" x 6" wood, carpet-covered bunks that are 10' 6" long spaced 40" apart when measuring from the outside edge of the bunks. They also require that the front end of the bottom bunk extend past the flat bottom of the boat. If you'd like to stick with the wooden bunks they recommend, we do sell the marine grade carpeting in the 18" width, # CE11349. If...

That is the case most of the time with this issue, usually it takes trial and error to determine exactly how much of your trailer should be underwater to find the sweet spot. I would recommend using part of the trailer (such as a fender) as a reference point for how much should be underwater to find the sweet spot. Another solution people have is to switch...

Jon,Thank you for your review. These boat rollers are made to be in water when getting the boat on and off of the trailer. When they are submerged for long periods of time it can cause some wear on the rollers. A better option would be galvanized rollers such as: part # DL21741 but even then they are susceptible to rust if underwater for long periods of time.
