Mechanical pushbutton combination lock

The Simplex 7104-03 is a fully mechanical lock that uses a pushbutton code for entry. It requires no batteries, wiring or electronic components to operate. The single access code is programmed at the keypad without removing the lock from the door. A deadlocking latch automatically relocks the door after each closing.

Adjustable backset and door thickness

The lock fits doors from 35 mm to 57 mm thick and offers an adjustable backset of 60 mm to 70 mm. It suits wood or metal doors in commercial or residential settings where a keyless, code-only solution is wanted. It does not suit buyers who need a keyed override, multiple user codes or electronic audit trails.

Bright Brass US3 (605) finish

The cast metal front housing carries a Bright Brass US3 (605) finish that resists force and matches traditional hardware. The clutch-protected exterior thumbturn adds durability against forced entry attempts. The 13 mm deadlocking latch and flat strike plate complete the installation on compatible doors.
