The XP99NL-US4-4 is a Von Duprin XP99 Series Extra Protection rim exit device with Night Latch trim in Satin Brass, sized for 4 Foot doors. Night Latch — outside knob locked/unlocked by key, always free from inside. Ships less cylinder — order a mortise cylinder separately to match your existing keyway.
ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Field reversible handing. The XP (Extra Protection) model features a reinforced shield over the mechanism case — designed for high-abuse environments where standard exit devices take damage.
Pro-Tip from Our Locksmiths: The Night Latch is the most popular trim for XP99 in school applications — teacher unlocks from outside with key, students push bar to exit. The XP model's reinforced case stands up to the daily abuse these doors take in high-traffic school corridors.
