Easy Install, Great Fit

Got the AC-100 for a Diamond C motorcycle trailer. Just extra insurance against the untrustworthy. Easy install. No spacers were needed. It fits great and keyed the same as my other Proven Lock.

Trailer lock

Everything went well for install . For a puck lock I thought would be a solid metal lock casing , come to find a really light weight aluminum possibly, hopefully deters the bad guys.

Great product👍

Dump trailer will now be ok to leave at jobsite with no worries. I will be getting more for the rest of the company trailers. Very heavy duty with quality combined is always a good thing!
