Master LockFits 1-7/8" and 2" Couplers - (4) Keyed Alike Trailer Coupler Locks 377KA-4

Spent $200 on six locks...tried 5 different trailers and NONE of them fit...all take a 2 inch ball...MAKE SURE your coupler has a lip otherwise these WILL NOT work

I bought a set of these. they are suppose to be chrome plated. THEY ARE NOT! the ones I received are grey and seem to be some cast material. They are not as heavy or strong as the chrome plated ones. I think I can easily break these will a hammer

Didn’t fit over the lip on my coupler so it was returned.

Strong. Durable. Key works well in it. Had 6 keys with the 3 pack of locks. All matching

They fit nice in the trailer. Since installation no one has tried to steal the trailers yet...….

Nice to have the trailers all under the same key

These are great locks at an affordable price. It is convenient to have all locks keyed alike.

I had to adjust my hitch to fit, but that was a good thing as my trailer rides better. It’s also nice that the three are keyed the same
