Product Description
9927L-17-F 4 US28 LHR Von Duprin 99 Series Classroom Fire Rated Surface Vertical Rod Exit Device in Anodized Aluminum
The 9927L-17-F 4 US28 LHR is a Von Duprin 9927 Series Surface Vertical Rod exit device with L-17 Lever trim in Anodized Aluminum (US28/628), sized for 4' doors. Classroom Function — outside lever is locked until unlocked by key, relocks automatically when door closes. 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 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 9927 field failures — five-minute fix that prevents a callback.
