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 a padlock (sold separately).

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:

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:

It works great. I use it with a disc lock. No problems. I like it




by:

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


Comments
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?
-- Etrailer Expert Jenny N - 01/04/2022
No it is not
-- comment by: Larry - 01/04/2022
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

$30.10
to complete the lock.

by:

Heavy duty design will act as a good deterrent. However, the weak link is the lock that is used to secure the device which cut with bolt cutters so there are no guarantees against theft.




by:

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.

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:

Best Locks in the Market. Super easy and durable !!!




by:

Product works great




by:

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




by:

Easy to order--quick delivery!




by:

Great Design




by:

Seems to be a loose sloppy fit on my 2” Bulldog, time will tell how secure this is.


Comments
This item works on 2 and 5 sixteen inch balls too so it will be a little loose on your 2 inch. Maybe you would feel more comfortable with a lock like item # BLTL-36

I've used these for years Functional. Effective. I have several trailers, using my own keyed alike locks I don't have to keep up with different keys for different trailers.




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


Comments
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.

The products sold by E Trailer is always the best and I have dealt with George for years and appreciate the fact that they look after the customers and NOT out just to make a buck, quality ownership of anything they sell.




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.


Comments
Still have my trailer and wheels. Thank you for checking in.
Steve K - 01/29/2015
Is it still working for you?
-- comment by: Rory - 01/15/2016


by:

I have 10 trailers use this with master lock discus shrouded stainless steel keyed a like locks works great for us




by:

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


Comments
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 # DT25013KA
Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers
$52.79
fastway universal trailer lock. Please keep in mind, the maximum coupler width must not exceed 4-3/4 inches to use DT25013KA.
-- Etrailer Expert Heather A - 09/28/2018

Appears that it will do the job. It's not very complicated, clamps on hitch to make trailer stay where you park it.




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


Comments
Make sure you have the Buldog hitch it will not work with wider ones with the flanges on them
Thomas - 08/26/2019


by:

love these. fit many trailer balls & I can use my own locks. Hole is a bit narrow for standard "Discus" locks, but 10 sec with a burr on the drill fixes that.




by:

Looks like good quality piece, just too small to fit my 2 5/16” tongue. The uprights that hold the pin will not fit around the tongue. I should’ve done my homework and ordered the TL 33.


Comments
The locking shroud has an inside width of 3-3/16 inches, so in order to fit your coupler would need to be narrower than that.
-- Etrailer Expert Mike L - 02/08/2019


by:

This fits my travel trailer hitch and I can use the padlock of my choice, which is the Bolt padlock.
