Product Description
9948NL-OP-F-US28-3 Von Duprin 9948 Series with 110MD Night Latch Fire Rated Concealed Vertical Rod Device in Anodized Aluminum
The 9948NL-OP-F-US28-3 is a Von Duprin 99 Series Rim exit device in Aluminum (US28/628), sized for 3' doors. Night Latch with Optional Pull — outside lever locks and unlocks by key with optional pull handle. 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: Rim devices are visible on the door interior, so they're typically used on utilitarian doors (back exits, service doors, storage rooms) rather than customer-facing entrances. But they're reliable, affordable, and quick to install — spec them when aesthetics aren't the priority.
