Product Description
EL9957EO-US28-4 Von Duprin 9957 Series Exit Only Surface Three Point Latch Device with Electric Latch Retraction in Anodized Aluminum
The EL9957EO-US28-4 is a Von Duprin 9957 Series Surface Three Point Latch exit device in Aluminum (US28/628), sized for 4' doors. Exit Only — push bar operation from inside only, no outside trim. Free egress from inside. No cylinder required for this function.
ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Field reversible handing.
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.
