The RXQEL9857L-NL-17 4 US3 LHR is a Von Duprin 9857 Series Surface Three Point Latch exit device with L-17 Lever trim in Bright Brass (US3/605), 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 + QEL — Combines Request to Exit monitoring with Quiet Electric Latch Retraction for full access control integration. 24VDC.

Pro-Tip from Our Locksmiths: The 9857 three-point latch device provides three engagement points — rim latch plus top and bottom bolts. This is your go-to for high-security applications or large doors where a single latch point isn't enough to keep the door sealed. Popular on data centers and clean rooms.
