Adjustable Coupler Bolt Lock Model AC-100

This is a must have and will go with any coupler lock.

Item arrived as designed, item looks well-built and seems like it will do a good job at protecting your trailer

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.
