Mechanical knob pushbutton lock
The Simplex 1021C-26D is a heavy-duty mechanical combination lock with a satin chrome finish. It provides keyless exterior access via a single programmable code while allowing free egress from the inside. The cylindrical latch carries a three-hour fire rating for labeled doors.
Door thickness and core compatibility
Verify that your door thickness falls between 35 mm and 57 mm before ordering. The lock requires a separately purchased LFIC Corbin Russwin 6-pin length core to operate; it will not function with other core types or without a core installed.
Adjustable backset and fixed ADA knobs
The adjustable backset covers 60 mm and 70 mm positions to match existing door preparations. Fixed ADA-compliant knobs and a unified trim plate are integrated into the cast front housing, removing the need for separate lever or trim purchases.

Questions about this item
Does the 1021C-26D include a Corbin Russwin LFIC core or must I buy it separately?
The lock is built for LFIC Corbin Russwin 6-pin cores; the core is sold separately and must be purchased on its own.
Which backset should I select for a door pre-drilled at 60 mm versus 70 mm?
The adjustable backset covers both 2-3/8" (60 mm) and 2-3/4" (70 mm), so one unit fits either preparation.
What does the 3-hour UL/ULC fire rating on "A" label doors mean for daily use?
The cylindrical latch assembly has passed a 3-hour fire test on "A" label doors, confirming it will maintain integrity during a fire event.
