I own and operate a trailer dealership, we have over 200 trailers in stock. I USE these locks. They fit EVERY type of coupler I have ever tried to put it on.  (except for goose necks) If you have a trailer, you need this lock. If you have more than one trailer, this lock will fit them BOTH! If you sell your trailer, and get a new one, this lock will fit it too!

It is very easy and quick to use, and can be locked in complete darkness (It is that easy!). Simply turn the key to unlock, slide the "ball" back. Put it up in the coupler, slide the "ball" back and turn the key to lock it.

SO EASY!

 
Fits 1-7/8", 2", and 2-5/16" couplers manufactured by Reese, Fulton, Valley, Atwood, Shelby, Putnam, Hammerblow, Bull Dog, Dutton Lainson, and UFP. 
Advanced locking mechanism resists picking and prying.
