Product Description
QEL98NL-OP-F 4 US10B Von Duprin Fire Rated Quiet Electric Latch (QEL) 98 Series Night Latch Office Rim Exit Device Oil Rubbed Bronze
The QEL98NL-OP-F 4 US10B is a Von Duprin 98 Series rim exit device in Oil Rubbed Bronze (US10B/613), 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.
Quiet Electric Latch Retraction — QEL motor-driven latch retraction provides quiet, ADA-compliant remote unlocking. 24VDC power required.
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: Hex key dogging is standard on non-fire-rated 98 rim devices. That means you can hold the latch retracted during business hours so the door operates as a push/pull. Fire-rated models delete dogging per UL code — if the customer needs doors to stay open on a fire-rated opening, budget for mag holders tied to the fire alarm.
