EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers

Just received this today. It’s extremely sturdy and getting a bolt cutter anywhere on this hitch lock looks impossible. I’m so far very impressed 698912

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. 485266

After 1 year, Still very Happy with this lock. It is on my trailer all the time, removed only to hook the trailer to the truck. Excellent, quality product!

Still very happy with the trailer Coupler lock

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. 369817

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. 398959

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

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! 160561

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

What an amazing lock! It’s not like the cheap garbage you buy locally. I know nothing is theft-proof, but it’s going to take an engineering degree to steal my trailer now! 582612

Fast and friendly service, exactly what I needed for my trailer. 577131

this will work perfect for me. I don't want some one to "borrow" my trailer. I got my trailer to haul my Vette out when hurricane's approach. Would like to thank George for being so quick and helpful on my purchase. 480597

Excellent service, fast delivery. Just what I was looking for to lock and secure my trailer. 471359

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. 450419

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. 440194

It's perfect 440132

It fit a little loose on the trailer. Maybe it can be fixed. Otherwise, a good product! 427019

This is a heavy-duty lock that fits my Bulldog hitch; most locks will not fit a Bulldog. 416698

nice product, price a little high for a piece of unpainted steel, also needs to be a left and right side for trailers, in Texas needs opening on left to light the licence plate. The people in sales were pleasant to talk with, product arrive as promised, nice experience, will by from them again, recommended. 387398

Very easy to install and a perfect fit, thanks. 371930

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! 340509

Nice lock but the main part doesn't look very strong. Looked a lot higher quality in the advertisement. 306570

Was surprised it was aluminum, should be steel

Great Service as always 306200

Seems like a very good lock for the bulldog coupler. I used it on my 2 5/16" coupler. Seems like it secures it very well. Sure if someone wanted to steal the trailer they could cut off the lock, but it would definitely take them some time. This will definitely slow down the process, and deter many. 292562

Great product, and great service by Etr ailer 289322
