Simplex LR-1021-B-26D-41 RH Cylindrical Pushbutton BEST Key Override Lockset

The dormakaba Simplex LR-1021-B-26D-41 is a new, mechanical (non-electronic, no battery required) pushbutton cylindrical lockset from the L1000 Series, configured for right-hand (RH) / right-hand reverse (RHR) doors with a BEST-compatible key override cylinder. The part number decodes as follows: "L" = lever trim, "R" = right-hand handing, "1021" = L1000 series cylindrical chassis with lever handle, "B" = BEST interchangeable core (IC) key override, "26D" = satin chrome finish (ANSI 626/US26D), and "41" = ADA-compliant lever style. The lock body accepts up to 1,000 unique user-programmable mechanical combinations using the 5-button pushbutton keypad without any electrical components, making it inherently fail-safe and suitable for stairwells, utility rooms, server rooms, and commercial interior doors requiring controlled access. This unit ships as a complete kit including the lever/keypad assembly, cylindrical latch, strike plate, mounting hardware, and installation instructions as confirmed by the photos; the BEST key override cylinder is pre-installed, and the satin chrome (26D) finish is corrosion-resistant and ADA-compliant per ANSI/BHMA A156.30.
