Product Description
99L-01-F 4 US28 LHR Von Duprin 99 Series Classroom Fire Rated Rim Exit Device in Anodized Aluminum
The 99L-01-F 4 US28 LHR is a Von Duprin 99 Series Rim exit device with L-01 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: Rim exit devices mount on the surface of the door without requiring mortise or internal routing. The 99 series rim devices are the easiest to install on retrofit jobs where door prep is limited. Great for quick code compliance upgrades on existing doors.
