Product Description
98ALK 4FT US4 Von Duprin 98 Series ALK Rim Exit Device Satin Brass
The 98ALK 4FT US4 is a Von Duprin 98 Series rim exit device in Satin Brass (US4/606), sized for 4' doors. Alarm Kit — audible alarm sounds when the exit device is activated. Deters unauthorized egress. No cylinder required.
ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Field reversible handing.
Pro-Tip from Our Locksmiths: Hex key dogging is standard on non-fire-rated 98 rim devices. That means you can hold the latch retracted during business hours so the door operates as a push/pull. Fire-rated models delete dogging per UL code — if the customer needs doors to stay open on a fire-rated opening, budget for mag holders tied to the fire alarm.
