Product Description
9975HL-US10-4 Von Duprin 9975 Series Hospital Latch Mortise Lock Exit Device in Satin Bronze
The 9975HL-US10-4 is a Von Duprin 9975 Series Mortise Lock exit device in Satin Bronze (US10/612), 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: Mortise lock exit devices (9975) require a mortise pocket prepped into the door edge. On retrofit jobs, verify the existing mortise prep is compatible with Von Duprin's 9975 body dimensions. A Schlage L-series prep is close but not identical — don't assume cross-compatibility.
