Product Description
9975EO-F-US4-4 Von Duprin 9975 Series Exit Only Fire Rated Mortise Lock Exit Device in Satin Brass
The 9975EO-F-US4-4 is a Von Duprin 9975 Series Mortise Lock 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: 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.
