The Schlage ND40S-LAT cylindrical privacy lockset combines heavy-duty Grade 1 performance with the clean, modern look of the Latitude lever. Designed for privacy applications, this non-keyed lockset is well suited for commercial restroom, dressing room, and similar interior doors where temporary privacy is needed without keyed access. As part of the ND Series, it is built for demanding institutional and commercial environments, offering strong construction, dependable operation, and broad door compatibility. Its cylindrical design supports straightforward installation while delivering the durability, security, and code-focused performance expected from Schlage commercial hardware.
Features
Functional Details
The ND40S privacy function allows the inside lever to be locked by push button for temporary privacy. The outside lever remains locked until emergency release is performed from the outside, and the inside lever always provides immediate egress. Closing the door does not automatically relock the outside lever unless the button is pressed again.
