Product Description
RX9827L-NL-06-F 4 643E LHR Von Duprin 98 Series Night Latch Fire Rated Surface Vertical Rod Exit Device in Aged Bronze
The RX9827L-NL-06-F 4 643E LHR is a Von Duprin 9827 Series Surface Vertical Rod exit device with L-06 Lever trim in Aged Bronze, 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.
Request to Exit — Request to Exit switch signals the access control system when the exit device is activated. 24VDC.
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 rods take more abuse than concealed rods because they're exposed. On high-traffic openings, check rod guides and bottom bolt alignment on every service call. A loose rod guide is the #1 cause of 9827 field failures — five-minute fix that prevents a callback.
