Product Description
9875NL-F-US32D-4 Von Duprin 9875 Series with 990NL-M Night Latch Fire Rated Mortise Lock Exit Device in Satin Stainless
The 9875NL-F-US32D-4 is a Von Duprin 9875 Series Mortise Lock exit device in Satin Stainless (US32D/630), sized for 4' doors. 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.
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 9875 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 9875 jobs, add time for mortise pocket verification and potential adjustment. Get it right and it's bulletproof — rush it and you'll be back.
