Von Duprin 990NLM26D Night Latch Pull Trim Mortise

Product Description

The VON DUPRIN 990NLM26D is a night latch pull trim designed for use with 98 and 99 series mortise exit devices. It provides a lever-pull handle on the exterior side of the door, allowing controlled entry while the exit device manages egress from the inside. The trim ships in a 626 Satin Chrome finish, which suits commercial aluminum door frames and stainless hardware environments. It measures 13.9 inches in length, 5.9 inches wide, and 4.6 inches in height, and weighs 2.3 pounds. Installation is performed by licensed locksmiths, door hardware specialists, or commercial contractors working on code-compliant exit hardware assemblies.

This trim is intended for commercial and institutional door applications where controlled entry and reliable egress are required. Typical installation scenarios include office buildings, schools, healthcare facilities, and other public-occupancy buildings where 98 or 99 series mortise exit devices are already installed. The night latch function restricts exterior entry to authorized users while maintaining free egress compliance on the interior push side of the door.
