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.

Works great for my Bulldog hitch! I'm satisfied it will stop anyone from tak8ng my trailer easily!

Yes,I would buy another one if I had another trailer with a Bulldog hitch!



by:

Good products and great service!
Tha
nks.

The product looks great, very nice quality.
Issue
I have is it was purchased to lock around a standard size Load Rite Boat trailer Coupler. It will not fit. Maybe 1/4" too narrow on the inside diameter This should be pointed out clearly, in the product description.
I think I can make the necessary modifications, but shouldn't have to do this.

This lock is meant to be used with the Bulldog Collar-Lok Couplers which do have a narrower coupler head than other locks. The lock that I would recommend for you that is used with trigger-style, latch-style, or handwheel-style couplers would be part # BLTL-33-40D. It is also a surround style lock for a coupler.

Product has held up very well and works as described. No complaints to date.



by:

I have used several versions of hitch locks and this is a very simple and secure lock which works well with any style of hitch. Definately would purchase again.



by:

Great idea. Quality part. But, it would not fit my trailer even after I modified it. Used the idea of this part to make my own that would fit.



by:

very satisfied with this product!



by:

Great product! Fits my trailer perfectly! I bought this item because I have my own lock to use. Would definitely recommend!



by:

Works Great !! I still have a trailer in my possession ! Lol



by:

I'm only giving this a middle of the road rating because it wouldn't fit any of my three trailers. I can't blame you or the lock for that.
It's the way my trailers are your lock are designed.
Undoubtedly I should have returned it, but didn't.
It's probably going into the next metal scrap run I make.
Again, not your fault. I should have studied the details closer.



by:

Good hitch lock thought it came with the padlock but it didn't that's ok works good



by:

I'm using an Abus "Diskus" 20/80 lock. Its shackle is radiused--nothing straight. I had to slightly relieve one side of the EZ Lock bolt hole to allow the 20/80 to fit through. A smaller Diskus or a "U" shackle lock would not need this.

I'm satisfied with the EZ Lock. It provides a reasonable deterrent to opening the Bulldog. I sometimes also use a cast stainless collar lock with another 20/80 depending on the neighborhood.



by:

This was a great choice for my trailer and piece of mind.
We all know if someone is really determined to steal something, it’s almost impossible to stop them.
However this product is a great deterrent that does not create a terrible inconvenience to the user.



by:

This is the best lock for a Bulldog Style hitch i have seen. We used this lock to integrate into our Master Lock Keyed Alike System. No more hunting up the missing key; time and money saver at work and at home.

Thanks

I have been very happy with my experience with etrailer.com. Great ion, Good Reviews,Good Prices, Good Product info, Great shipping and customer service. Also, alot of the items are hard to find, its nice to have a one stop shop.



by:

This theft deterrent works just fine, super easy to use WHICH MEANS YOU SHOULD USE IT !!! Any theft system is really to stop the person that is not fully prepared to steal something. So using this is 80% of the solution to having your trailer borrowed permanently. Easy to put on and you have to use the disk style lock as this is the only lock that can't be cut into by bolt cutters. Do not use a cheap pad lock or the thieves will go at the WEAK part of the system.

Is it still working for you?

Did not fit my trailer with 2 5/16 ball. Throat was too narrow to go over trailer hitch.

I wanted to reach out to you in regards to your review on the coupler lock. You mentioned that the lock did not work for your coupler. I wanted to ask you if your coupler is a Bulldog Collar-Lok-style coupler?

Larry

No it is not

This lock is meant to be used with the Bulldog Collar-Lok Couplers which do have a narrower coupler head than other locks. The lock that I would recommend for you that is used with trigger-style, latch-style, or handwheel-style couplers would be part # BLTL-33. It is also a surround style lock for a coupler. You would need a padlock like part # ML40D to complete the lock.



by:

Received my Trailer Hitch Lock right away as usual. I am not sure it would stand up to sawsall or a portable grinder with a cutoff wheel. It appears to be built very well. E-Trailer is awesome and make purchasing a breeze



by:

Good product but not usable on my hitch which is compound locking. Good only for the standard lever lock hitch.

The lock part BLTL-20 is designed for bulldog collar-lok couplers. If you have a traditional style latch lock on your coupler I recommend part # TMX47FR Trimax universal trailer lock. Please keep in mind, the maximum coupler width must not exceed 4-3/4 inches to use TMX47FR.



by:

The coupler lock is a great idea!
Easy
to use, and made from light weight cast aluminum.
The lock pin will accept any standard sized padlock.
I like that the lock pin also covers hitch latch, to prevent tampering.

Pros: Light weight, small, simple, good finish, easy to use, cast aluminum wont rust or corrode.

Cons: Cast aluminum, could be quickly cut through with hacksaw.

Locks only keep the honest people from stealing your stuff, but its better than not having any lock.



by:

works only for very specific hitches with very very narrow flange around the ball area. make sure the dimensions work for you. Mine sit on the shelf unused

Make sure you have the Buldog hitch it will not work with wider ones with the flanges on them



by:

Work great! Just what we needed to help protect our trailers.



by:

We had to do some modification because we accidentally purchased the wrong one but it is working great now that we have got it to fit.



by:

Hi Guys,
Well my Hitch Lock was as I
expected and that is great. The service was wonderful and etrailer is a fine company for all my Hitching problems. The service was excellent and so was the delivery. I hope you will continue to give that same kind of excellence that I had to all you customers.
Sincerely,
John Bon



by:

The bees knees for locking up a BullDog trailer hitch. Just be sure not to skrimp on the lock for this. Get the lock that does not expose the shackle to a crook's bolt cutters!



by:

Bought for my son who just bought a trailer for his four wheeler . I didn't want his trailer sighted to be stolen, the guy he bought it from had it stolen before it was recovered and locked!! This lock will detour theives prowling for an easy steal!! Thanks for having a product that's affordable and easy to connect !!



by:

the blaylock bulldog style receiver lock is just what I had hoped.they say it is made from hd aircraft aluminum and I have no cause to doubt that.the lock rod is hardened steel.although it has not been tested(theft attempt)it does give me peace of mind when I leave home. it seems to be a fine u s made lock and fits good,is easy to put on and remove.i'm happy with it.
