Hi Splash Man!

The Master Lock Set - Coupler Ball Lock, Locking Hitch Pin, and Coupler Latch Lock # ML44VR will actually fit 1-7/8", 2", and 2-5/16" couplers, so you are good to go there! It's pretty versatile.

That said, they are not able to be keyed alike, unfortunately. This goes for all the kits like this we have. All the pieces included with it are the same key number though. There is a chance that ordering two will end up having the same key numbers, but there is a pretty wide variety of key numbers and that chance is fairly low.

What kind of trailers are you wanting to lock up?

Hey Splash Man, did you end up using the Master Lock set for your trailers? It’d be great to hear how it worked out with the different coupler sizes. Your experience could help others looking for a similar lock setup.
