Simplex L1011RH-3 Brass US3 Mechanical Lever Pushbutton Combination Right Hand Door Lock

Right-Hand Mechanical Lever Combination Lock

The Simplex L1011RH-3 is a heavy-duty cylindrical lock with a pushbutton combination keypad and fixed ADA-compliant lever. It provides keyless exterior access while allowing free egress from the inside. The lock features a Bright Brass US3 finish and a unified trim plate for a clean appearance. It carries a three-hour UL/ULC fire rating for A-label doors.

Check Door Thickness and Backset Before Ordering

Verify your door thickness falls between 35 mm and 57 mm to match the lock's fitting range. Confirm the backset is either 60 mm or 70 mm, as the adjustable latch accommodates only these two measurements. Ensure the door preparation suits a cylindrical latch with a 13 mm by 19 mm latch length. The lock is handed right-hand only and cannot be field-reversed.

Suits Commercial Doors Needing Keyless Entry

Ideal for offices, schools or multi-tenant buildings that require a single programmable access code without the cost of key management or battery changes. Not suitable for left-hand doors or openings outside the 35 mm to 57 mm thickness range. Buyers needing multiple user codes, audit trails or electronic credential support should look at alternative access-control systems.
