This Blaylock EZ Lock is designed to work with Bulldog Collar-Lok couplers that fit 1-7/8", 2", or 2-5/16" hitch balls. After it has been secured, this coupler lock renders your trailer's coupler inoperable, ensuring peace of mind.
With the slanted side of the lock pointing toward the front of the coupler, simply place the coupler lock's raised ball up under the coupler and into the coupler's ball hole. The sides of the lock will surround the coupler. Slide the 3/4" diameter pin through the holes in the lock and secure the pin in place with the included Master Lock padlock.

Fight back against trailer thieves with this rugged, rustproof aluminum trailer coupler lock. Simple yet effective, it deters towaway theft of your trailer that has a Bulldog Collar-Lok coupler. Includes stainless steel padlock.by: Todd 10/25/2023
I tried other trailer locks without success , this lock fits great. very well made .
by: Y-Lee Kioti06/25/2017
This lock system is simple and weather exposure should not be a hindrance for removal when needed.
I would like to see the pin made of hardened steel. May get a machinist to fab one up out of a harder Rockwell rating.
Painted it Orange and it contrasts very well to the black trailer frame.
This is a visual que for those passing by the county road, that the coupling has 'something' on it.
The Master lock appears to be of a higher quality the the same design but sold for storage unit use. It may be made by Master but have no way of knowing. The lock operates very smoothly and the stainless body is perfect for outdoor application.
A shout out to Jennifer who has been providing excellent customer service from day one.
This means I will use etrailer for future trailer needs, thanks to her.
Hope this helps others.

One year in with many camping trips, we are very happy with the coupler lock. This lock fits the bulldog style coupler well, and the master lock has worked well through rain and shine.

Coupler lock shipped/arrived quicker than expected and works as intended.

I lost the metal rod 6 months ago, can not use the lock any longer!

Hitch clearance was a little to tight for my stacker trailer but easy to modify, other than that it worked great

I have a bulldog style 2 5/16 hitch on my dump trailer, this fits perfect. Looks like its heavy duty.
by: Joe L.04/20/2017
We have several trailers we use to haul equipment to job sites and have to leave them at site over night so these locks are very sturdy which gives us security from theft and was able to get all locks keyed alike so one key works on all trailers which is convenient.

Great product, perfect fit for my bulldog hitch. Everyone that sees it comments about what a strong lock it is. It is easy to use and just its looks is a huge deterrent.
It is easy to put on and take off. I am glad I found EZ Lock Trailer Coupler Lock for Bulldog Collar-Lok Couplers. I would definitely buy it again!

Love the lock. I lost my first one and had to purchase a second one - been more careful with it. It is a great lock. Ive had several people comment on it and want one like it so Ive referred them to you guys.Thanks for the follow-up.
by: Ray07/25/2021
The product is well designed and I'm sure would work on many/most couplers. However I have an Equal-i-zer 4-point weight distribution hitch with sway control, and the EZ Lock simply won't fit. The Equalizer is too large and the EZ Lock wasn't designed to give enough clearance to get on there. So I wasted my money.
Buy this if you have another configuration, but be forewarned if you have what I have and avoid this product.

I done some research about this and similar products and found this product to be the best bank for the buck. made to fit my Bulldog hitch. It is used by folks that sell trailers, I thought that was good enough for me...

Very good lock heavy well built buy it you will like it
by: Steve H05/12/2020
I am very pleased with the tongue lock. I use it on my boat trailer which I often leave in a Marina for several days at a time while the boat is in a slip. I tend to think of it like all deterrents, another layer of security to overcome which will encourage movement towards an unlocked trailer hitch. It works well, seems sturdy and accomplishes the purpose.
by: Chuck 09/12/2021
It is a very good lock for a standard ball trailer. Lock has a reasonable quality Master short shackle key lock with 2 keys.
Very easy to use
I recommend you routinely (every 3-6 months) lubricate the lock with graphite or WD-40 to prevent the lock and shackle from binding.

- Recommended Collar Style Trailer Coupler LockThe EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers # BLTL-20 is what I recommend for your style coupler as long as it fits the dimensions. This coupler is 3-3/16 inches wide and 4 inches tall. It is roughly 2-5/8 inches tall to the bottom of the 3/4 inch pin. If you want this with the padlock, then use # BLTL-20-40D instead.

- What is The Interior Height Of The EZ Lock Trailer Coupler Lock BLTL-20?The EZ Lock Trailer Coupler Lock # BLTL-20 is 2-5/8" from the base of the ball to the bottom of the lock pin.

- Difference Between Blaylock TL-20 and TL-33 Coupler LocksSure thing! The EZ Lock Trailer Coupler Lock # BLTL-20 is for Bulldog Collar-Lok-style couplers while the EZ Lock Trailer Coupler Lock # BLTL-33 is designed for Fulton, Shelby, Dutton-Lainson, Atwood, and similar couplers. I've attached some review videos for you to check out.
view full answer... - Coupler Lock Recommendation for a Bulldog Collar Lok CouplerThe Bulldog couplers are usually the collar-lok style couplers so you would need to go with a different coupler lock than the # BLTL-33 that you referenced. Instead you would wan the part # BLTL-20-40D as it is specifically designed for collar lok Bulldog coupler. I attached a review video for you to check out as well.
view full answer... - Coupler Lock Replacement Option For TowSmart Pro Class With Missing KeysI have a replacement option, but there isn't replacement barrel keys for your TowSmart Pro Class Coupler Lock. If you've lost the key's you'll need to replace the lock all together. I recommend going with the EZ Lock Trailer Coupler Lock # BLTL-20-40D that way if you ever lose the lock again you can replace just the lock, and not the entire assembly.
view full answer... - Coupler Lock for Atwood 2-Inch A-Frame CouplerThe Blaylock EZ Lock Trailer Coupler Lock # BLTL-20-40D is specifically meant for use with Bulldog Collar-Lok-style couplers such as # BD028381. For your Atwood 2-inch A-frame coupler you can instead use part # BLTL-33 and lock part # ML40D.
view full answer... - Coupler Lock Recommendation for a Bulldog Collar-Lok CouplerYes, check out the EZ Lock Trailer Coupler Lock # BLTL-20-40D. This coupler lock is compatible with Collar-Lok Couplers and should work well with the Bulldog Collar-Lok Adjustable Channel Mount Coupler # BD028657 you referenced.
view full answer... - Hitch Lock Recommendation for Bulldog A-Frame Collar Lok CouplerFor your Bulldog Collar Lok coupler part # BD028499 we have the Blaylock Coupler lock part # BLTL-20-40D which was designed specifically for your coupler so it would work great. I attached an install picture and review video for you to check out as well.

- Recommended Lock for Bulldog Collar-Lok CouplerFor your trailer with a 2" Bulldog Collar-Lok coupler I recommend the EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers # BLTL-20-40D. The Amplock you referenced fits a different style of Bulldog coupler. The Blaylock EZ Lock is specifically designed for your coupler style. Once it is attached, the coupler will be inoperable providing you with the security you are looking for.
view full answer... - Lock Recommendation for Bulldog Collar-Lok Trailer CouplerI'm assuming you have a Bulldog Collar-Lok trailer coupler like the # BD028244 you'd looked at. Blaylock makes a lock specifically designed for a Bulldog Collar-Lok trailer coupler, part # BLTL-20-40D. The lock includes the lock assembly itself as well as the locking pin and disc padlock. I'll link you to a demonstration video featuring the # BLTL-20-40D coupler lock.
view full answer... - Best Coupler Lock for Bulldog Cast Head 2-5/16 CouplerThere are a couple of options for very high-quality coupler locks for the Bulldog cast head coupler, with the absolute best being from AMPLock: - AMPLock Trailer Coupler Lock for 2-5/16" Ball Couplers w/o Lip # AMP34FR This lock is a beast for a number of reasons, starting with its ductile cast iron construction. Ductile cast iron is just not going to be something a thief is able to cut through or smash off it is far, far too strong for that and often used in things like automotive parts...
view full answer... - Coupler Lock Recommendation for Use with Demco Channel Tongue Trailer CouplerYes the coupler part # DM13689-52 that you referenced is lockable. For a pin style lock the part # 28012 would work well. Or for a lock that goes around the coupler opening the part # BLTL-20-40D would be a great option. I attached review videos for both locks.

I pulled up pictures of your trailer and wasn't able to verify that this was the style of coupler that the trailer had, but it's also very common for trailers to have the couplers swapped so you may have a Collar Lok style coupler like what I attached a picture of. If you have a different style of coupler we...

- Lock Similar to Blaylock that is Steel Instead of AluminumAluminum is a softer metal so if you were worried about it getting cut through quickly, and I don't fully blame you, I'd go instead with the FastWay lock part # FA86-0015-317 which is steel and a similar design. This also fits nearly all coupler styles too which makes it very versatile.
view full answer... - Trailer Coupler Lock Compatible with Wide CouplerIf you have a Bulldog Collar-Lok Coupler, then the EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers # BLTL-20-40D is your best option. If you want the pin style coupler lock, then the Bulldog Easy Access Coupler Lock - Swivel Head - Chrome # BD580409 is the largest span option at 3-5/8 inches.

- Best Keyed Alike Fastway Universal Coupler LockI have a solution for you, and we have several lock assemblies that can be keyed alike, but the one you were looking at item # BLTL-20-40D can not be keyed alike. I recommend the Fastway Universal Coupler Lock Key 316 item # FA86-0015-316. This coupler lock also fits 1-7/8", 2" and 2-5/16" couplers. I have linked our entire selection of couple locks that can be keyed alike as well as a couple of review videos for this lock.
view full answer... - Lock For Bulldog Collar-Lok CouplerWe do have a lock that will work for your Bulldog 4BWC-AR coupler, which is the Collar-Lok coupler similar to part # BD028462. What you can use is the following: - EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers # BLTL-20-40D This comes with the lock that will surround the coupler and a padlock made from stainless steel with a hardened steel shackle.

- Coupler Lock Recommendations for a RAM Brand TrailerIf your RAM brand trailer has a collar-lock style coupler like the Bulldog Coupler # BD028444 yes the EZ Lock Trailer Coupler Lock # BLTL-20-40D would be an excellent choice as a trailer lock. A more universal coupler lock that we offer is the Fastway Coupler Lock part # FA86-0015-318. I attached review videos for both coupler locks for you to check out.

view full answer... - Is There A Universal Coupler Lock That Can Be Keyed AlikeGreat question. EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers # BLTL-20-40D. We are unable to key alike the locks that come with the EZ lock trailer coupler. However, we can key alike the fastway trailer coupler. To do so you will select key alike from the drop down menu the select how many you would like to purchase. It is that easy. Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-318.
view full answer... - Coupler Lock Recommendation for Trailer with 4 inch Wide CouplerWe have a solution that will work great but the part # BLTL-20-40D would not be what you'd need as it is designed to fit a Bulldog Collar Lok coupler and is only 3-3/16 inches wide. The # FA86-0015-318 would instead be what I recommend as this fits all standard coupler sizes like what you have.

- Recommendation for a Coupler Lock for a Collar-Loc Trailer CouplerFor a Collar-Lok coupler I recommend a lock designed for then such as # BLTL-23 (2-5/16 inch ball), # BLTL-20-40D (1-7/8 to 2-5/16 inch balls), or # BLTL-22 (2 inch ball).
view full answer... - Comparing Different Types of Coupler LocksWe have a variety of locks for your coupler, each with their own applications. If you have a fat lip coupler, I recommend the etrailer Trailer Coupler Lock - Flat Lip, part # e98897. This yellow lock can fit a 2" coupler and is an immediate deterrent as the color quickly grabs attention. The lock has a stem that reaches into the coupler and can't be wiggled free. If you don't have a fat lip coupler but still want a lock that reaches into the coupler, I recommend the EZ Lock Trailer Coupler...

still a great solid product. Spray some silicon in the lock about every few months and all works well.
