Fight back against trailer thieves with this rugged, rustproof aluminum trailer coupler lock. Simple yet effective, it deters towaway theft of your trailer that has a Bulldog Collar-Lok coupler. Padlock sold separately.


Features:

  • Coupler lock deters theft of your trailer that has a Bulldog Collar-Lok-style coupler
  • Heavy-duty bracket fits around your trailer's coupler
    • Raised ball on platform sits inside of coupler
  • Steel pin slides through the bracket to secure the lock to your coupler
    • Padlock (sold separately) is required to secure pin in place
  • Aircraft-grade, lightweight aluminum construction is strong and resists wear and corrosion
  • Made in the USA


Specs:

  • Application: most 1-7/8", 2", and 2-5/16" Bulldog Collar-Lok-style couplers
  • Overall dimensions: 2-1/2" long x 4-1/2" wide x 5" tall
  • Inside width: 3-3/16"
  • Pin diameter: 3/4"
  • Weight: 4-1/5 lbs


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).

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

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
$66.74
fastway universal trailer lock. Please keep in mind, the maximum coupler width must not exceed 4-3/4 inches to use DT25013KA.

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 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.

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.

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 558454

Good lock at a much better price than the competition. This lock has a little rougher finish than more expensive locks, but my trailer has never complained. 527603

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

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 363250
