Need serious security for a gate, shed, or interior door? This GATEMATE rim lock is built tough. It's a premium double locking bolt mechanism, meaning it has a deadbolt that locks in two places for extra security. The finish is a combination of stainless steel and black, giving it a robust, no-nonsense look. It has a 2-inch (50mm) backset, which is a common measurement for many door preparations. Inside, it uses a 6-pin lock barrel, which is more pick-resistant than simpler locks. The package includes the stainless steel bolt shoot (the part that goes into the door frame), all the necessary stainless steel fixings for installation, and 5 keys – great for handing out to family or keeping spares. It's a rim lock, so it mounts on the surface of the door rather than inside it, which can make installation easier on some doors. A solid, reliable choice for when you need a lock you can count on to do its job day in and day out.
