The XP99EO-F-US28-4 is a Von Duprin XP99 Series Extra Protection rim exit device in Aluminum, sized for 4 Foot 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. UL listed for up to 3-hour fire-rated door assemblies. Hex key dogging standard. The XP (Extra Protection) model features a reinforced shield over the mechanism case — designed for high-abuse environments where standard exit devices take damage.
Pro-Tip from Our Locksmiths: The XP99 Extra Protection model is built for high-abuse environments — schools, hospitals, correctional facilities. The reinforced shield over the mechanism case resists hammering and prying attempts that would damage a standard 99 series. If you're speccing for a building where vandalism is a concern, the XP is the right call. Fire-rated XP99 devices get UL listed for up to 3-hour fire doors. The fire-rated version uses a top latch with fire bolt that auto-latches on closing — make sure the door and frame are also fire-rated to maintain the assembly's listing.
