Schlage ND80PDEU Spa 622 Electrified Cylindrical Lock

Product Description

The SCHLAGE ND80PDEU SPA 622 is a Grade 1 electrified cylindrical lock configured for storeroom function, designed for commercial access control applications requiring reliable fail-secure operation. It accepts 12 or 24 VDC input and holds the latch locked by default until an electrical signal is applied to release it. The Sparta lever handle provides a clean, functional profile, and the conventional cylinder allows standard key operation. The flat black coated finish (622) offers a durable, low-reflectance appearance suited to commercial interiors. This lock is installed by licensed locksmiths, security integrators, or commercial door hardware specialists.

This lock is intended for commercial or institutional doors where controlled egress and storeroom-style access are required. In a storeroom configuration, the outside lever is always locked and can only be operated by key or electric release, while the inside lever provides free egress at all times. With a 2-3/4 inch backset, it fits standard commercial door preparations. Typical install scenarios include server rooms, utility closets, pharmacies, and secured office areas where access must be tightly controlled.
