If you can use one of our standard barrel-type locks, and if the box is at least 2.75” deep and if there is sufficient room for the device on the faceplate, our PB13 style keyswitches will mount quickly and easily even if there are no factory weld studs. The only field modification required is to drill a round hole .75” in diameter. The kit will come with adhesive-backed anti-rotation plates for either horizontal or vertical mount, and a surface-mounted 1.375” diameter escutcheon for identification. These are available on-line in the Parts Department.

Most standard fixtures mount to wall boxes that are 3.50” deep.

Innovation I-Line? fixtures mount flush to the wall, and project 1.375” from the surface.

With the exception of the flat fire service I-Line? keyswitch, our standard barrel-type keyswitches require a minimum clearance of 2.75”. Custom made and specialty keyswitches vary.

Traditional style push buttons require a minimum clearance of 2.00” deep. 
Innovation I-Line? push buttons require a minimum clearance of 1.125” deep.

No, the longest screws we stock are 2.00” long.
