Video Transcript for Dutton-Lainson Boat Trailer Roller Bunk Bracket Installation

Today on our boat trailer we're going to review and install the Dutton-Lainson Boat Trailer Roller Bunk Bracket part number DL21742; this is applicable in conjunction with both 4 and 5 foot Dutton-Lainson Roller Bunks part number DL21740 and part number DL21741. To begin our install we're going to remove the old or manufacture's boards and brackets. Since we're removing the bunk boards and brackets we just going to take the u-bolts off the frame. Quick check tip, before you remove your board take a tape measure and get the height of your board. That way when you install your new brackets and rollers you can set it back to the same height. Now that we have the boards lose we'll go ahead and just take them off the trailer and set them aside as they will not be reinstalled. Now for our new rollers we're going to have the Dutton-Lainson Boat Trailer Deluxe Roller Bunks part number DL21741. Now for our new Rollers we're going to install a new bracket to secure it to the trailer.

We're just going to reuse the old manufacturer's u-bolt. Once I have it set in place I'm going to go ahead and tighten it down. Note, for additional security we could add a second set of u-bolts here on the other side. Now here at the center support we're going to have 2 5 foot rollers come in together; we'll need 2 brackets. Both getting attached to the same spot; to do that we'll bring in a u-bolt from each side. This will secure our brackets.

Now I've got my first one in place, the back side here of the center support. We'll get our second u-bolt and support bracket. Now that all our hardware is in place we'll make sure she's in position and then tighten down the u-bolts. Keep in mind when tightening down your u-bolts make sure you tighten them down evenly. Now once we have the center support done we'll go ahead and install our last bracket here at the very end.

It will be the same process for the very first bracket. Now with all our brackets secured we'll go ahead and put our bunk rollers in place. Starting here at the rear set of bunk rollers we'll set it onto the brackets first. Not supplied with the install kit you'll need to add a bolt or bolt and washer for this application that'll go down through your bunk roller then through the bracket. Underneath I'm going to add a flat washer and nut. It's recommended to use nylon lock nuts; this will help prevent the hardware from loosening.

Let's go ahead and install it finger tight this time. Now we got our attachment point in place we'll go ahead and the same process here for the rear attachment point. Next, we're going to install our front bunk and rollers. It'll sit here on our forward and second bracket but because of how close we are oriented to the rear bunk we going to remove the rear set of rollers and we'll need to drill out our attachment point so that we can secure it to the bracket. Let's start with removing the rollers. Using a couple of 3/4 inch sockets we can simply just go ahead and remove the bolt that holds the rollers in place. I'm just going to slide the rollers back onto my bolt, thread that nut back on; that'll hold them together while I set them aside. Now I'll go ahead and put our front bunk in place. Set it in position on the bracket and mark the hole. Now we'll take our bunk back off, we turn it over and drill out the hole. To drill out the hole I'm going to use this small poly bit and then open it up to my final size using the step bit process. We now ready to go ahead and put the bunk back in place, drop in our hardware and secure it. Now with all our hardware in place we'll go ahead and tighten down all our fasteners. Now with one side done we'll do ahead and repeat the same process on the other side. Just like that we've completed the install of the Dutton-Lainson Boat Trailer Roller Bunk Bracket part number DL21742 on our boat trailer.

Boat Trailer Roller Bunk Bracket for Dutton-Lainson Roller Bunks

by:

Poor design lifts rollers 2 inches higher than 2x4 bunks. Modified everything and had to throw away u bolts



by:

5 Ft roller bunk Part DL21741 is a high quality item. It installed in minutes on existing brackets. Boat is approx 3/4” higher than on standard bunks but it shouldn’t be a problem since it rolls on/off effortlessly. I also bought new brackets Part DL21742 thinking they might allow lowering boat a little but they were same as existing brackets so I returned them which was simple. Customer service was excellent.



by:

Due to a mix up in shipping....nobody's fault really, another type of bracket was required. The exchange was done without a hassle and the proper part is ready for installation. The product is better than expected but the customer service exceeded any I have ever dealt with anywhere!

Have had these installed and used for a year now....boat loads and launches with ease. Could have saved to much time and money....no more ulcers and stress!!



by:

The brackets are as described but unfortunately given my trailer frame I couldn't mount my roller bunks any lower than the standard bunks. The lowest you can get these brackets is probably almost 4 inches above the frame, then you have to bolt the roller bunks on top of that.



by:

Had to drill out the rivet and replace it with a bolt/lock nut for a aluminum older boat to fit correct.



by:

To keep the same height as the old boards, the backets would need cut and possibly welded to the frame. I raised the bracket just high enough to install the U-bolts. Now, the rollers will not till as designed. Shouldn't hinder loading and unloading but I will see first time out



by:

used 5 & 4 ft. Deluxe roller bunks. on boat trailer, easy install and boat rolls off trailer very easily. Great product!! Boat is much easier to launch and load.



by:

I used these brackets with the roller bunks and they made installation a breeze paired with the recommended u-bolts. The system literally went together in less than an hour with minor modifications I opted to make. I cannot wait to pick up my new boat and put them to the test.



by:

I purchased these about a year ago and again just a few days ago. Used these on a boat I sold and then just bought 4 to set up my buddies boat with roller bunks. Very strong and sturdy bracket, works with the roller bunks great.



by:

Used these as part of a full boat trailer rebuild. They were sized perfectly and of very high quality. After a year of use these are performing excellently.



by:

I have always been impressed with the quality and timeliness of delivery from etrailer.

  • Roller Bunk Recommendations for a 16 ft Boat Trailer with 8 ft Wooden Bunks
    Since your current roller bunks are 8 feet in length I would recommend you get 2 sets of 4 foot long roller bunks like the Boat Trailer Deluxe Roller Bunk # DL21740. I would mount them down the middle of the bunks and if you used two sets of the # DL21740 there would be rollers from front to back on your bunks. Although they are not required for installation you may be interested in purchasing Roller Bunk Brackets # DL21742 for installation of the roller bunks.

  • Replacement Roller or Carpeted Bunks for a Boat Trailer
    You could so with 2 sets of the 4 foot rollers, # DL21740, and either have the extra foot or trim them to length. Ideally you would want rollers anywhere the boat rests on bunks. These roller bunks can be attached directly to a flat surface or you can use bracket # DL21742 (4 needed per set). We also have carpeted bunks, 4 feet long, all ready to be installed, # CE27810.

  • Can 5 Foot Long, 3,000 Pound Capacity Roller Bunks Support a 5,000 Pound Boat
    The capacity per set of roller bunks, # DL21741, is 3,000 pounds. A 5,000 pound boat would be too heavy even though not all of the weight would be applied to all of the rollers all of the time. You would need additional support to ensure that nothing fails. Additional rollers placed side by side could be one solution. The rollers can mount directly to a flat bunk or you can use brackets, # DL21742 (4 per pair of rollers).

  • Recommendation for Adding Bunk Rollers or Replacing Current Bunks with Rollers on Boat Trailer
    Assuming that your bunk rails are at least five foot long, I would recommend using the Dutton-Lainson Boat Trailer Roller Bunks, # DL21741. This system includes 2 - 5ft sections with a 3,000 pound weight capacity and offers universal mounts to attach either vertically or horizontally.

  • Is Installation Hardware Included with Dutton-Lainson Roller Bunks
    The roller bunks # DL21740 and # DL21742 do not include the mounting hardware. You will want to use corrosion resistant hardware such as galvanized or stainless steel fasteners, since it is for a marine application. The hardware is not included because there are different ways to mount the bunks, direct or using brackets, so they did not include hardware. You will need to decide what works best for you and your trailer.

  • Can Roller Bunks be Attached Directly to Wooden Bunks

No hardware is included with this part. To install the roller bunks to your trailer, you may be interested in the Dutton-Lainson roller bunk bracket, part # DL21742.

  • Replacing Wood Bunks with Roller Bunks on a Boat Trailer

    On the Boat Trailer Deluxe Roller Bunk, # DL21741, you are correct, you will need 3 sections per each 16 feet long carpeted bunk.

    You are correct, you can mount the Boat Trailer Deluxe Roller Bunks, item # DL21741, directly to the top of your existing wooden bunks. If mounted in this fashion you would not need any brackets. I would recommend stainless steel mounting screws, available at a local hardware store, to attach the roller bunks to your wooden bunks.

  • Will Deluxe Roller Bunks Work with Dutton Lainson Bunk Bracket # DL21584
    On Boat Trailer Deluxe Roller Bunk, # DL21741, the bracket width is 1-7/8 inches and the wheel to wheel distance outside to outside is 4-3/4 inches. The bracket designed for use with these roller bunks is # DL21742. The inside width of bracket # DL21584 is also 1-7/8 inches. So it could potentially work but the rollers and this bracket were not designed for use with each other so I cannot say if it will work out or not.

  • Do the Dutton Lainson Roller Bunk Brackets Include Mounting Hardware
    The Boat Trailer Roller Bunk Bracket # DL21742 that you referenced is not sold with any mounting hardware. You will need to provide the hardware needed to install these brackets plus bunks like the 5 foot Roller Bunks part # DL21741 to your trailer.

    The best option in my opinion is to use the Dutton-Lainson Boat Trailer Deluxe Roller Bunk - 5' Long Sections - 12 Sets of 3 Rollers # DL21741 which will allow you to angle the set farther up the trailer to help you center the hull but I recommend using a keel roller like the CE Smith Deep V Keel Roller Assembly for Boat Trailers - Galvanized Steel/Black Rubber - 5" # CE10401G to help center the boat.

    I did some research on your 1994 Sylvan Pontoon boat and found that the beam is 8-ft.

I have attached a photo that shows how the bunks are placed under the pontoons. If your trailer frame is wide enough to be able to place the bunks with those dimensions then you would not need to try and extend the axles. You may want to...
