Easy install.
Nice little lock. I was kinda surprised how it works with an internal screw lock. However, it's very easy to install and might deter theft.

Solid
Purchased this as a spare for my boat trailer. Glad I did cause I needed it. Now I use it constantly. Solid material and definitely helps deter theft. Would be very difficult for someone to cut through this to get it off.

Leaves a small gap
The screws are a little offset from the key so you cannot completely tighten it and remove the key...a little attention on the machining setup would prevent this.

The lock coupler works well on my utility trailer when I need to make sure it is secure on my vehicle. I do find the key/lock a bit tricky to remove the key from (stiff). Given the price and how I am using it - it does the trick
