The 9957L-NL-03 3 313 LHR is a Von Duprin 9957 Series Surface Three Point Latch exit device with L-03 Lever trim in Duranodic Dark Bronze (313/313), sized for 3' 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.
ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Factory set LHR, field reversible.
Pro-Tip from Our Locksmiths: When servicing a 9957 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.
