The 98ALK 4FT US28 is a Von Duprin 98 Series rim exit device in Satin Aluminum (US28/628), sized for 4' doors. Alarm Kit — audible alarm sounds when the exit device is activated. Deters unauthorized egress. No cylinder required.

Pro-Tip from Our Locksmiths: When quoting 98 rim devices, check the frame for strike compatibility. The 98 uses a standard rim strike, but on hollow metal frames you may need a longer lip strike if the frame rabbet is deeper than standard. Most callbacks on rim devices are strike alignment — get it right at install.
