The Schlage ND40S-OME cylindrical privacy lockset is a heavy-duty Grade 1 solution designed for commercial openings that need dependable privacy control without a key. Built on the trusted ND Series platform, this lockset combines the Omega lever design with rugged construction for high-traffic applications such as offices, restrooms, and interior rooms. The ND40S privacy function allows the inside push button to lock the outside lever, while emergency access remains available from the outside when needed. With UL listing, ANSI Grade 1 performance, and field-reversible handing, this lockset is made for long-term reliability in demanding environments.
Features
Functional Details
The ND40S privacy function is operated by a push button on the inside rose. Pressing the button locks the outside lever, and closing the door keeps the outside lever locked. The inside lever always opens the door and releases the button automatically. Emergency entrance from the outside is possible with the appropriate privacy release.
Included Components
ND Series cylindrical lockset components are supplied for standard commercial installation, including the chassis, lever trim, latch, strike, and mounting hardware as outlined in the manufacturer catalog.
