PDQ SD126 MEM Passage Function Cylindrical Latchset
Function Information:
- Latchbolt operated by lever from either side at all times
- ANSI F75
The PDQ SD126 MEM is a premium Grade 2 Cylindrical Latchset engineered for high-traffic areas where locking is not required. Featuring the popular Memphis (MEM) lever style, this latchset provides a clean, modern aesthetic that is fully ADA Compliant. It is the ideal choice for interior office doors, hallways, and common areas that require effortless, reliable access.
As a Passage Function (ANSI F75) unit, the SD126 ensures that both the interior and exterior levers are always active. There are no locking mechanisms, providing a "set and forget" solution for doorways that serve as primary thoroughfares in commercial or institutional buildings.
Architectural Quality for High-Traffic Corridors
The PDQ SD126 is built to withstand the rigors of a professional environment. Designed with a heavy-duty cylindrical chassis, this latchset offers smooth operation and a firm spring return that prevents lever sag even after years of constant use.
Standardized for commercial applications, it features the industry-preferred 2-3/4" backset and a 4-7/8" ASA strike, making it a seamless retrofit for standard hollow metal and wood doors.

Why the PDQ SD Series is the Professional Choice

- Safety and Accessibility: The MEM lever’s "returned-to-door" design prevents the handle from catching on clothing or equipment, a critical feature for high-traffic hallways and emergency egress paths.
- Durability: The zinc-dichromated steel chassis provides superior corrosion resistance and internal strength, ensuring the latchset handles hundreds of thousands of cycles.
- Handing Required: The Memphis (MEM) lever is handed. Specify the door hand (LH or RH) when ordering; the latchset is prepared for the specified hand using standard commercial door preparation.
Handing: The Memphis (MEM) lever is handed and must be ordered for a specific door hand. Please specify LH (left hand) or RH (right hand) when ordering Lever. For the Memphis lever, handing is about which way the lever curves relative to the hinge: LH = LHR and RH = RHR (the lever curves up toward the hinge, not down)
