Great lock and well made.
This is one of the best receiver locks that I have ever owned.
Works great, is good quality which I believe should last .
As a result, the SXT3 did not have a long enough spread to work with my receiver.
I recommend these locks to others and suggest purchasing the stainless steel version to prevent rust/corrosion (and keep the locking mechanism lubricated).
I bought this after buying my new truck and although this lock claims to be able to fit a Class III, IV and V receiver, it lies!
It is too short for a Class V, it doesn't stick out enough to able to lock the cap on.
Last time I removed the lock I had to soak the lock in penetrating oil and lightly heat pin with a torch, this was the only way I could get the key to turn.
I used this for a set of led back-up lights mounted for a receiver.
I have a 2013 Ram 3500 with the Class V hitch and the hitch is too wide for this product.
