Fire Exit Hardware is to be installed on Fire Doors
bearing the marking “Fire Door to be equipped with Fire
Exit Hardware” Any retrofit or other field modification to
a Fire Rated opening can potentially impact the Fire
Rating of the opening.
IMPORTANT:
• Use supplied templates for field installations.
• Use door preparation documents for door/frame manufacturing.
• Door must be properly reinforced where the exit device chassis
and latches are mounted. The surface must be flush and flat
within ¹⁄16" (1.5 mm).
• Prepare the door and top and bottom door edges using the exit
device templates or door preparation and instructions.
• Prepare the exterior of door using the trim template or door
preparation and installation instructions.
• All threaded holes require a minimum metal material thickness
of 0.125" (3 mm).
• We recommend samples be used to verify preparation before
mass door or frame manufacturing.
• NOT RESPONSIBLE for any physical or property damage due to
incorrect / improper preparation or installation.
