The LD98K-US4-3 is a Von Duprin 98 Series Rim exit device with Latch Detector (LD) and Knob trim in Satin Brass, sized for 3 Foot doors. Knob Trim — Night Latch function. Outside knob locked/unlocked by key, always free from inside. Ships less cylinder — order a mortise cylinder separately to match your existing keyway.
Latch Detector — monitors the latch bolt position and reports status to the access control panel. 24VDC. ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Field reversible handing.
Pro-Tip from Our Locksmiths: Knob trim with Latch Detector is common in retrofits where the building has knob hardware throughout. The LD gives you door status monitoring that probably wasn't there on the old hardware — a good upgrade path.
