Product Description
9957EO-F-US4-4 Von Duprin 9957 Series Exit Only Fire Rated Surface Three Point Latch Exit Device in Satin Brass
The 9957EO-F-US4-4 is a Von Duprin 9957 Series Surface Three Point Latch exit device in Satin Brass (US4/606), 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.
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: 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.
