Night Latch — outside lever locks and unlocks by key, inside always free for egress. Ships less cylinder — order a mortise cylinder separately to match your existing keyway.
Chexit Alarm — Chexit delayed egress alarm — provides a 15-second delay with audible alarm before allowing exit. 24VDC.
Fire Rated — UL listed for use on fire-rated openings. Mechanical dogging is deleted per UL code on fire-rated models. Field-reversible handing.
Pro-Tip from Our Locksmiths: The 9975 mortise lock exit device combines exit device push bar with a mortise lock body recessed into the door edge. This gives you the latching security of a mortise lock with code-compliant panic hardware. Popular on storefront doors where you need both security and life safety.
