How to measure your door
Most North American doors use one of two lock preparations. Find yours, take two or three quick measurements with a tape measure, and you'll know exactly which Prodillo locks fit.
Deadbolt door (round holes)
- Door thickness: measure the edge of the door, front to back. Most exterior doors are 1-3/4".
- Backset (A): from the door edge to the center of the deadbolt hole. It's almost always 2-3/8" or 2-3/4".
- Bore hole (B): the round hole through the door, usually 2-1/8" across.
Best fit: V Series, V Series Handle Set or S80.
Mortise door (lock in the door edge)
- Door thickness: front to back. Prodillo mortise smart locks fit doors from 1-3/8" to 4-1/4" thick, depending on the model.
- Backset (A): from the door edge to the center of the key cylinder. Common sizes are 2-3/8" (60mm) and 2-3/32" (53mm).
- Center distance (C): from the center of the handle spindle to the center of the key cylinder. Prodillo mortise locks use 85mm (3-11/32").
Best fit: G2, MS01, R3 or Z10.
Lift your handle to lock the door? You likely have a multi-point lock, which is common on fiberglass and patio doors. The G2 and MS01 both work with multi-point locks.
