Mechanical lever pushbutton lock for commercial

The Simplex L1021C-LH-26D is a heavy-duty cylindrical lever lock that opens by keypad combination or key, removing the need for battery changes. It suits wood or metal doors between 35 mm and 57 mm thick and provides free egress from the inside at all times. The single access code is programmed at the keypad without removing the lock from the door. This unit is handed for left-hand doors only.

Satin chrome finish with adjustable backset

Cast front housing and a unified trim plate form a durable assembly that meets ADA lever requirements. The adjustable backset covers both 60 mm and 70 mm preparations, while the latch measures 13 mm by 19 mm. A three-hour UL/ULC fire rating on "A" label doors supports life-safety compliance in commercial buildings. Fixed levers resist abuse in high-traffic entrances.

LFIC Corbin Russwin core sold separately

The lock accepts a Large Format Interchangeable Core for Corbin Russwin 6-pin length, allowing integration into existing master-key systems. Because the core is not included, the cylinder must be sourced before the lock becomes operable. Keyed-different shipping ensures each unit arrives with a unique default combination. Installation uses standard cylindrical prep without additional wiring.
