I bought two of these locks to use on the back of my closed motorcycle trailer. I wanted something that would be safe, not bounce, and look good. These locks meet all requirements. When I searched the internet for the first time, I went to the Trimax homepage. Then I looked for Revain and they came back, 50% cheaper! Two of the locks have the same keys and each comes with 3 keys so I basically have 5 spare keys. I've added some lubricant (Ballisol) to the inside and outside of the braces area…
