Product Description
9927L-NL-16-F 4 US28 RHR Von Duprin 99 Series Night Latch Fire Rated Surface Vertical Rod Exit Device in Anodized Aluminum
The 9927L-NL-16-F 4 US28 RHR is a Von Duprin 9927 Series Surface Vertical Rod exit device with L-16 Lever trim in Anodized Aluminum (US28/628), 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: Surface vertical rod devices (9927) have rods visible on the door surface running to top and bottom bolts. When measuring for replacement, check rod length — 3' and 4' doors need different rod kits. Also verify header and threshold strike condition before quoting.
