Mechanical pushbutton lever lock

The Simplex L1021C-RH-3 is a heavy-duty cylindrical lock that opens by keypad combination or key. It mounts on right-hand doors between 35 and 57 mm thick and suits wood or metal construction. The mechanical design removes the need for battery changes and uses a single code set at the keypad.

Adjustable backset and latch

An adjustable backset covers 60 mm and 70 mm positions with a 13 mm by 19 mm latch. The lock carries a three-hour UL/ULC fire rating on A-label doors. Builders needing a different backset range or a longer latch throw will need another model.

LFIC Corbin Russwin core required

The lock accepts a large-format interchangeable core for Corbin Russwin six-pin length, sold separately. Without that core the cylinder cannot be keyed. Buyers who want a pre-keyed cylinder or a different core format must choose another product.

Questions about this item

Will the L1021C-RH-3 fit my existing door prep with a 60 mm or 70 mm backset?

Yes, the adjustable backset covers 60 mm and 70 mm, matching common cylindrical cut-outs.

How can I verify the lock is functioning correctly after installation?

Enter your programmed code; the lever should retract the 13 mm x 19 mm latch smoothly, and the door must latch securely when closed.

Does the box include a Corbin Russwin 6-pin LFIC core, or must I purchase it separately?

The core is sold separately; the lock ships with the cylindrical housing, unified trim plate, fixed ADA levers, and adjustable latch.
