Another For The Road
Bought my 5th puck lock to use on the side door of my enclosed trailer. These are great locks and these black locks match my black trailer perfectly. I gave them all keyed the same as well.

Great locks and USA made
I ordered and received quickly 2 Puck locks and the 5th wheel lock. I started by ordering Amazon Chinese puck locks. They were heavy and didn't fit my toy hauler latches. I received the Provenlock pucks and they lighter and fit perfectly. The 5th wheel lock is great and fits well. Also, being keyed all the same is great too. Good stuff and USA made.
