The 9857L-US3-4-LHR is a Von Duprin 9857 Series Surface Three Point Latch exit device in Bright Brass (US3/605), 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.

Pro-Tip from Our Locksmiths: When servicing a 9857 three-point latch, check all three latch points independently. A misaligned top or bottom bolt can cause the whole device to bind. Adjust strikes one at a time, starting with the rim latch, then top, then bottom.
