Product Description
99ALK 4FT US3 Von Duprin 99 Series ALK Surface Vertical Rod Exit Device Bright Brass
The 99ALK 4FT US3 is a Von Duprin 99 Series Rim exit device in Bright Brass (US3/605), 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: Rim exit devices mount on the surface of the door without requiring mortise or internal routing. The 99 series rim devices are the easiest to install on retrofit jobs where door prep is limited. Great for quick code compliance upgrades on existing doors.
