Model 2178

Great improvement from the older model

I just got the new model 2178 for my new boat trailer and it’s a way better improvement from the older model I got since it wouldn’t hold my safety chains in the lock as designed.

Great Quality for extra piece of mind

Expensive? Yes. Worth it? Absolutely!! This lock is built like a tank! It’s super heavy duty and I have total faith that it would hold up to or deter a possible thief. Plus they have amazing customer service and support. I highly recommend a Proven Lock. You will not be disappointed!

One Flaw - Great Locks

This company is fantastic; but there is one flaw in the design, the puck lock is very difficult to unlock because the key is inserted from the bottom, which is nearly impossible for especially myself. I understand it protects from weather but again the design could be best if worked from side. Otherwise it is great to keep my two trailers exactly where I put them.
