High quality lock. I bought another brand first and was disappointed with the quality. This one is well built, spins smoothly, and even has a gasket to seal the mounting surface. The 5/8" Tgi length is good for replacing the thumb latch on a modern Airstream battery door. This does not include the flat/straight cam lever (comes with a couple of different offset levers). I reused that , which I had on my thumb latch.
