Why the Backset Size Matters

The backset is the distance from the edge of the door to the center of the lock cylinder. Choosing the wrong size means your lock won’t align with your door frame or handle set — leading to a latch that sticks, a bolt that doesn’t engage, or a handle that won’t fit at all.

Fits Your Grisoll Smart Lock? Yes.

This mortise body is the exact internal mechanism used with Grisoll’s smart lock lineup. If you’re installing a new Grisoll smart lock, this is the compatible mortise lock body. It’s also compatible with most third-party European smart locks and traditional key cylinders, making it a universal upgrade for any hinged door.
