Video Transcript for Blaylock Industries Trailer Coupler Locks - Surround Lock - BLTL-20 Review

Today were going to review part number BLTL-20. This is the EZ Lock Trailer Coupler Lock. This coupler lock is designed to prevent theft of your trailer. This is a simple installation. Basically a heavy duty bracket will secure around your trailers coupler. The raised ball on the platform will sit inside your trailer coupler and then will fit on your trailer coupler.

The 3/4-inch diameter steel pin will slide through the bracket and over the coupler and then when you put a lock through here that would actually lock the coupler in place to keep it from coming off. Now it does use a padlock. It is sold separately. I have an example of one we sell which is the Disc-Style Padlock, part number DT40124. I just want to show you.

If you open that up, run the lock through it that will lock that pin over the coupler. Now the pin hole is designed to fit on a 1-7/8-inch, 2-inch, 2-5/16 Bulldog Collar-Lok Style Coupler and I want to show you that type of coupler. This is a Bulldog Collar-Lok. Its different than any of the other locks or the couplers. Basically this one is if you lift up on the latch, as you can see, as I lift up on the latch, it will release the collar.

Its spring loaded. It pops out to allow you to put it onto the ball. What Im going to do is demonstrate it on this lock here. If we put this onto the--if this coupler was on your trailer, you put that on and when you install this you want the slanted side to point towards the front of the trailer. Slanted sides pointing towards the front.

Basically you just touch it back down and then to lock it into place, you take the 3/4-inch pin, put it over the coupler and put the lock into place. As you can see, it locks it in there. That will keep the coupler from being connected to another hitch ball. Nobody will be able to attach to it. This lock itself is an aircraft grade lightweight aluminum construction which is strong and will resist wear and corrosion. The part is made in the USA. Now it does fit most trailers with the 1-7/8 inch, the 2-inch and the 2-5/16 Bulldog Collar-Lok Style Couplers, just like this one here I demonstrated. Again, the locking pin diameter is 3/4 of an inch. A few measurements on this, the width is 4-1/2 inches. The length is 2-1/2 inches. The overall height is 5 inches. Again, this part is made in the USA. After your coupler has been secured, this lock will render your trailer coupler inoperable which will ensure inaudible 0:03:35. Again, I just wanted to reiterate when you install this, the slanted portion which you can see here, the coupler would be back here and the slanted portion would be facing the front of the trailer. That should do it for a review on part number BLTL-20.

The trailer lock doesn't fit my trailer. 608058


Comments

The inside width of this coupler lock is 3-316 inches, so it will not fit couplers that are wider than that.

Good product but not usable on my hitch which is compound locking. Good only for the standard lever lock hitch. 569690


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

fastway universal trailer lock. Please keep in mind, the maximum coupler width must not exceed 4-3/4 inches to use DT25013KA.

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. 114977

Excellent product, fast shipping and built to handle! This is no cheap plastic trailer tongue lock, very heavy duty and will accept any standard lock, which I needed to interchange lock keys on occasion. Highly recommended and etrailer is the only place I could find this type of lock. 639382

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. 611867

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. 603316


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.

Simple and easy to use, after looking at other locks I am glad I chose this one ! While no lock is foolproof this one will slow someone down awhile anyways, others looked like a wack or two with a hammer would render them junk. Not so with this one. 483535

Fits the Bulldog couple and allows me to use a keyless combination lock. Looks like it would take a little time to cut off so would make someone think twice before taking the trailer. 186040

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. 172255
