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.

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

After a lot of research I decided on the Bulldog Coupler lock because I really liked the design and materials that it was made of.



- BLTL-20-40D
by:

What's to say? It's a big 'ol chunk of metal that protects from thievery. I had to do a touch of grinding on the trailer tongue flange to allow the mechanism to fully clear. No biggie. Good value for the protection you get. If someone really wants your trailer, this could be defeated, but for general protection it works great.

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.

The fit is perfect for the bulldog coupler. It should keep unwanted thieves away, I feel safer about leaving my trailer unattended

I highly recommend This lock, along with the offered MasterLock padlock to anyone wanting to secure a trailer with a Bulldog hitch. I am very pleased with the quality & workmanship of this product to help secure my Horse Trailer hitch.

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... ordered one with the master lock from e_trailer received in in just a few days as stated as for pricing ...you won't be it by much if any!

lock bracket seems real secure but is a little more trouble than old ,old style ...throw on a lock and your done.

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.

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!

We purchased this lock as the locks we previously were using the lock kept getting stuck and the key would not open the lock and we ended up having to saw off the lock. This lock has worked perfectly and we will only be purchasing this lock for our other trailers!

etrailer was excellent in updating me on my order and delivering on time. The trailer coupler lock worked exactly as expected. I couldn't ask for more.

After a year there is no change. It works just as I expected. It has been off and on my trailer multiple times, stored in the elements, and it shows no signs of wear.

The purchase of this product was a terrible idea. Its made of cheap aluminum, that flexes and bends. The key for the lock snapped off in the lock, full disclosure, I dont know why, could have been my fault, but it broke pretty easily..... This lock is a mild deterrent at best, I wouldn't trust it on a trailer worth anything more than the lock is worth.

  • Coupler Lock Recommendation for Trailer with 4 inch Wide Coupler
    We 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 couplare and is only 3-3/16 inches wide. The # DT25013KA would instead be what I recommend as this fits all standard coupler sizes like what you have.

  • Coupler Lock Recommendations for a RAM Brand Trailer
    If 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 # DT25013KA. I attached review videos for both coupler locks for you to check out.

  • Coupler Lock that Will Fit 34 1995 Airstream Excella 1000 Travel Trailer
    If your 1995 Airstream Excella 1000 Travel Trailer has a Bulldog Collar Lok style of coupler on it then yes, the EZ Lock Trailer Coupler Lock # BLTL-20-40D would fit and work well. 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...

  • Lock Similar to Blaylock that is Steel Instead of Aluminum
    Aluminum 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 # DT25013KA which is steel and a similar design. This also fits nearly all coupler styles too which makes it very versatile.

  • Coupler Lock for Atwood 2-Inch A-Frame Coupler
    The 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.

  • Trailer Coupler Lock Compatible with Wide Coupler
    If 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.

    I'm sorry you don't find the Reese Tow and Store Lock Kit # RP7014700 to be acceptable. Based on your description it sounds like you are focused on the coupler lock and we have very positive reviews on this product. However we do offer a wide range of each product to allow you to determine the best fit for your needs and budget. I have linked the page to all of the options to assist. I personally like the Fastway Universal Trailer Coupler Lock # DT25013KA and that is my recommendation...

  • Recommended Collar Style Trailer Coupler Lock
    The 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.

  • Recommendation for a Coupler Lock for a Collar-Loc Trailer Coupler
    Master Lock coupler lock # 3784DAT is not the best option for a Collar-Lok coupler. For 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).

  • Comparing Different Types of Coupler Locks
    We 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 Lock Recommendation for a Bulldog Collar Lok Coupler
    The 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.

  • Lock Recommendation for Bulldog Collar-Lok Trailer Coupler
    I'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.
