Simplex LR1011-26D-41 Grade 1 Right-Hand Mechanical Pushbutton Lever Lock

The Simplex LR1011-26D-41 Mechanical Pushbutton Lever Lock provides combination-controlled access for commercial and institutional doors without requiring keys, batteries, or electrical connections. Manufactured by dormakaba as part of the Simplex L1000 Series, this Grade 1 cylindrical lock features a five-button mechanical keypad and lever-operated latch mechanism. Users enter the authorized combination to operate the exterior lever, while the interior lever permits unrestricted exit without entering a code. The lock supports one programmable access combination, which authorized personnel can change through the keypad without removing the lock from the door. Its combination-entry-only configuration does not include a key override, passage function, or electronic credential interface.

The LR1011-26D-41 features a heavy-duty cylindrical lock housing, cast front assembly, vandal-resistant metal pushbuttons, and fixed ADA-compliant levers. Its standard locking mechanism incorporates a 1/2-inch (13 mm) throw deadlatch with a 2-3/4-inch (70 mm) backset and floating faceplate. The exterior housing measures approximately 7-3/8 inches high by 3-1/8 inches wide, with a 3-13/16-inch projection. Finished in satin chrome, ANSI/BHMA 626 (US26D), the lock accommodates commercial door hardware applications requiring a durable metallic finish. The L1000 Series includes a 3-hour UL/ULC fire-rated cylindrical latch for appropriately labeled fire doors and meets applicable accessibility requirements through its fixed lever design. Manufacturer specifications identify a three-year limited warranty.

Designed for office entrances, employee-only areas, storage rooms, utility spaces, educational buildings, and commercial facilities, the Simplex LR1011-26D-41 provides controlled entry where a shared mechanical access code is appropriate. This configuration is factory-handed for right-hand and right-hand reverse doors and is not field reversible. It installs on compatible wood or metal doors measuring 1-3/8 to 2-1/4 inches (35-57 mm) thick, with a minimum recommended door stile of 5 inches (127 mm). The lock uses standard ANSI/ASA 161 cylindrical door preparation with additional through-holes and a compatible strike plate. Its mechanical construction supports interior and exterior applications without requiring a power source, network connection, or electronic access control panel.

The Simplex LR1011-26D-41 incorporates a mechanical combination chamber designed for access code changes while the lock remains installed. Authorized personnel use the manufacturer-prescribed combination change procedure to update the single access code, eliminating electronic programming equipment and battery maintenance. The five-button keypad, heavy-duty lever assembly, and mechanical latch mechanism support repeated operation in commercial environments. The standard package includes the lock assembly, required installation hardware, an installation manual, and a full-scale mounting template. The LR1011-26D-41 differs from the LL1011-26D-41 primarily in door handing, with the LL model configured for left-hand applications. Installers must verify handing, door thickness, latch preparation, and fire-door requirements before installation.
