Perfect fit, just the lock I needed

Perfect fit. Exactly what I needed to replace an old lock similar to this one. If you buy one, when locking your hitch, make sure the cylinder is engaged and locked. It is easy to assume it is locked when it is not.

Good solid receiver lock in two sizes

Securely connected my cargo tray to my Subaru. Having both the 1/2 and 5/8 means I can use an adapter tow hitch easily without needing to buy another set of locks. The swivel head receiver lock rotates easily, and doesn't rattle.

A bit more expensive for the master lock than required for my needs but no other option was available
