Does exactly what I bought it for. The pin is long enough to go through the hitch and ensures that it doesn't wiggle loose. This gives me peace of mind, and is more secure than a bolt with a nut on it.92540

The locking mechanism is stiff and the key is very difficult to get in all the way. This might get better with usage. Overall, good product to use on any kind of trailer.17368
