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.

Pro-Tip from Our Locksmiths: The 9975 is the most complex exit device in the Von Duprin lineup. It has the most moving parts and requires the most precise door prep. When quoting 9975 jobs, add time for mortise pocket verification and potential adjustment. Get it right and it's bulletproof — rush it and you'll be back.
