This is a simple to use and secure lock for my new trailer. The Blaylock coupler lock will not rust and the MasterLock SS padlock works perfectly with it. Worth the peace of mind. Good service from etrailer and I would use them again.



by:

I like the build and quality of this coupler lock. It's great that I don't have to worry about it rusting, and definitely feels like it would deter most theft attempts. I'm sure it could be taken off with enough effort and heavy tools by someone motivated but that can be said for many coupler locks.



by:

Was missing padlock, called and etrailer sending another out.



by:

Item was returned. Poor shape to the ball and it would not go on my trailer



by:

Very solid. Multiple holes provide ability to fit and the small ball locked it in place. I had some difficulty attaching one but was able to get it with multiple attempts. I’m confident my flatbed trailers are now secure. etrailer assistance is very helpful.

The locks I bought have provided the security and confidence because my trailers have been stored in a remote area. My step son even bought one for his trailer. Good product for reasonable price.



by:

Have used one of the Receiver Locks on a flat bed trailer and it works fine. Haven't tried the one we bought for a bale trailer as the trailer is still hooked to the pickup. Fast service. Box was damaged but everything was in it.

Locks are working fine and we like them



by:

Super heavy duty! Solid steel bar. Solid steel lock. As everybody knows if a professional thief wants your trailer they’re gonna get your trailer. But if it’s parked on private they don’t want to get shot trying. The point of these locks is to cause the thief to skip your trailer and steal another. That works for me.

Still use and rely on it.



by:

I ordered 4 of these keyed alike. I live on a small peninsula surrounded by saltwater, my old locks rusted up and became useless. This lock setup is beefy and shouldn’t rust i I p on me. The shipping was fast and keyed alike option is great.

The coupler locks are perfect. They’ve been used in a coastal environment for a year and no corrosion issues.



by:

One solid piece of Hardware ! wow the service was excellent - i ordered on a Sunday and got ship notification that is was shipped out on Sunday - who works on Sundays ? these guys do ! Can't wait to get it on my boat trailer at the lake, only asset that is not secured - now i will sleep with no worries - 60 bucks to secure a $2,000 trailer is a no brainer - get one !

Excellent device, worth the peace of mind



by:

Easy to attach to my 19' travel trailer. It's bigger than I expected and It seems a little loose, but should provide enough deterrence to stop thieves. The Master lock is a perfect addition.

After one year, its still working out well. This product should last a lifetime.



by:

This is a great hitch lock, it fits all my trailers, so I ordered another one. I use it on my rv to help secure it as I live in a rural area with. The hitch is easy to use and is adjustable to fit most if not all hitches.



by:

While it states it can be used up to 2-5/8, the ‘ball’ end of the lock isnt big enough for the hitch to hold it; with the hitch mechanism fully closed it just falls out!?! Would be great if it did as I would also throw a lock on the mechanism for added Security... not impressed!?!



by:

Nice sturdy hitch lock, bought a cheap Reese style hitch lock and lost the key and was able to drill the lock mechanism out faster than unlocking it with a key, this system has a better idea with the master lock, about as good as your going to get to keep the thieves away who don't have a grinder to cut the hitch lock off the hitch



by:

Solid lock - seems like it would be harder to remove with brute force than the typical u-locks for trailers.



by:

It looks well built but it didn't fit my camper



by:

I am very pleased with the products I have purchased online from etrailer.com They have an excellent line of products to choose form and the short videos about each product are very helpful. Etrailer.com communications with their customers is very good and delivery of products were on time. The products I have purchased have been of high quality.



by:

I have been very impressed with this locking system for my trailer - Would definitely buy another one if needed



by:

excellent product. i can rest easy now that my boat and trailer are protected with the Blaylock trailer coupler lock.



by:

I like this lock. It is beefy and will be a theft deterrent. It is also simple to install and remove. I found that the _inside_ dimension is 5.5 inches wide - the outside width is 6.5 inches. It just fits the coupler on my trailer. It would be even better if it were painted bright red or orange.



by:

This is the third one I have purchased. We have three trailers and needed a third one. I think it is the best lock on the market. I have had two other styles and with a hammer they could be broke off. Not with this one.



by:

I got the lock this afternoon and my trailer has not been stolen yet!!

Michael

Very well



by:

Just bought a travel trailer, put the coupler lock on there and feel secure with that on there. Fits nice and snug. Thanks



by:

fits perfect



by:

Easy to use, adds one more deterrent to would-be thieves. Light weight, good for those of us trying to keep towing weight down. Showed up a day earlier than predicted by etrailer.



by:

Solid, versatile product... I can only wonder how many thousands of dollars I could have saved on stolen trailers over my career had we had something this uniformly usable along the way....

  • Recommended Lock for a Demco EZ Latch Coupler
    For the Demco EZ Latch Coupler like item # DM37ZR that does not have a lip around it you would want the Fastway Universal Trailer Coupler Lock item # DT25013KA. This is by far the best and most compatible option of the ones you listed. If you have more than one coupler you are needing a lock for you can select keyed alike and order as many locks as you need and they will all be controlled by the same key. I have linked a review video below.

  • Is the Blaylock EZ Lock Trailer Coupler Lock Only Used When the Trailer Is Uncoupled
    The Blaylock EZ Lock Trailer Coupler Lock part # BLTL-33-40D is only for use when the trailer is not connected to the tow vehicle. If you are looking for a locking device that will work while coupled you can just use a standard pin lock like the etrailer Pin Lock part # e98886. If you want both types that have the same key then go with the Reese Tow and Store Lock Kit part # # RP7014700.

  • Coupler Lock for Dexter DX12.5 (Model 10) Actuator with Wide Lip
    The Master Lock Trailer Coupler Lock # 377DAT you purchased can accommodate a max coupler width (including lip) of 4 inches , so for a lock that works with up to a 4-3/4 inch coupler width, I recommend the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33-40D. I pulled our Titan Model 10 actuator # T2477600 (Dexter DX12.5), and found that it measures just over 4-5/8 (4.63) inches edge to edge of the coupler lip, so the BLTL-33-40D will definitely be wide enough and work perfectly with your...

  • What is the Strongest Coupler Lock and Locking Pin That Will Fit My Square Coupler
    I do have a recommendation for a coupler lock for your square coupler. I recommend the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-318. I recommend the Fastway Universal Lock because it is made to fit various couplers, including square ones like yours. Also, the bolted lock is internal to prevent prying and the key mech is rounded to make it more difficullt to pick. Finally, it fits couplers up to 4" wide and the shackle is 6" long top to bottom,...

  • Will Blaylock EZ Lock Trailer Coupler Lock fit UFP Square Bodied Coupler
    If the front part of your square-bodied coupler is approximately 3 inches tall, based on the inner dimensions of the lock the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33 will work well for you. The # BLTL-33 has inner dimensions of 3-1/8 inches x 4-3/4 inches, when the bar is installed in the tallest position. Another factor to consider is the location of your coupler latch. The key is securing the lock in the underside of the coupler while also covering the latch on top of the coupler...

  • TL 33 and TL 45 Blaylock Trailer Coupler Locks
    I believe what you're looking for is the Blaylock EZ Lock Trailer Coupler Lock for 1-7/8", 2", and 2-5/16" Couplers # BLTL-33-40D. This has the TL 33 and then what I could find on the TL 45 is that it's the same part as the circular padlock on this coupler lock. This has an aluminum construction so it will hold up really well to the elements and it fits a wide variety of couplers on the market. Attached is a sample installation video for you to check out.

  • Inner Dimensions of the Blaylock EZ Lock Coupler Lock # BLTL-33
    I pulled the Blaylock EZ Lock Coupler Lock, # BLTL-33, from our warehouse and took some measurements for you. The inside width of this coupler lock is 4-3/4 inches. From the base to the bottom of the pin, it measures 3-1/8 inches (see photo). If you do not have a padlock yet, I recommend looking at the Blaylock EZ Lock Coupler Lock with Padlock, # BLTL-33-40D. This is the same coupler lock, but it includes a stainless steel padlock. You could also just purchase the lock separately as...

    There is a coupler lock available for your 1-7/8" Shelby coupler, though they locks themselves aren't truly "universal;" oftentimes they say they will fit "most" but will name specific brands and types they fit. For example, the Master Lock Universal Trailer Coupler Lock # 379DAT will fit a 1-7/8" straight lip, rolled lip and surge brake/hydraulic couplers from Shelby, but also from Reese, Fulton, Valley, Atwood, Shelby, Putnam, Bulldog, Dutton-Lainson and UFP.

    For a lock for your lipless cast coupler I recommend the Blaylock EZ Lock Trailer Coupler Lock for 1-7/8", 2", and 2-5/16" Couplers - Aluminum # BLTL-33-40D. This lock has 3 pin hole positions for a tight fit on a variety of couplers and uses a stainless steel padlock with a hardened steel shackle to secure the pin in place.

  • Best Coupler Lock For Titan Model 10 Coupler for 2-5/16 Hitch Ball
    The best trailer coupler lock for your Titan Model 10 Brake Actuator # T2478100 is the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33-40D because it locks your actuator with a stainless steel padlock that has a hardened steel shackle and busting through it would require not only a lot of time, but some significant tools. An everyday thief would have no chance of coming away with your trailer if you have this lock on your Titan actuator. For added security so you will always be able to...

    It sounds like you have an Unique Functional Product 2-5/16" square coupler which was bought out by Dexter. The MegaHitch Coupler lock part # UF35-946510 is designed to fit the standard sized coupler so it will most likely not be wide enough or tall enough to fit the square coupler according to Ultra-Fab.

    The EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers # BLTL-20 is specifically designed for a collar lock style coupler like # BD028657. For a standard travel trailer, you most likely do not have that style coupler, so I recommend the Blaylock EZ Lock Trailer Coupler Lock for 1-7/8", 2", and 2-5/16" Couplers - Aluminum # BLTL-33 for the same style that is compatible with most travel trailer coupler styles. If you want one with a padlock included, I recommend...

    I was unable to find a combination system that would work to lock both the coupler on your trailer and also the hitch receiver on your 2013 Dodge Ram 2500 with a 2-1/2 receiver. For a simple system to secure your coupler I recommend the Blaylock EZ Lock Trailer Coupler Lock, part # BLTL-33-40D. This lock simply inserts into the the coupler and uses a 3/4 inch pin to secure the lock to the coupler. A keyed Master Lock is included that is inserted through the pin on the lock. For a hitch...

  • Recommended Coupler Lock for the Titan Model 20 Brake Actuator
    I do have an option for you but the release handle on the Titan Zinc-Plated Brake Actuator part # T4750720 is going to limit the use of some coupler locks like the MegaHitch Lock Coupler Vault Pro part # UF35-946510. Instead, I recommend the Blaylock EZ Lock Trailer Coupler Lock part # BLTL-33-40D. In order to break though this lock you would have to cut though a 3/4" thick hardened steel pin which is easier said than done. This would require power tools but if a would-be thief does have...
