OPERATING ZONE

You Can Save Time And Effort If You First Establish All The Facts About

The “Operating Zone”

The “ Operating Zone” is the area surrounding the door opening, extending upward and backward as far as the door will travel. We call it the Operating Zone because it is the area that the door will have to operate within and the dimensions are critical and must be known in advance of a door and operator installation.

D - Backroom (depth into room) Manual lift = Door height plus 18” Operators = Door height plus 48”

E - Jambs must be plumb and solidly attached to the building. Floor must be level or exact gradeline established before you start.
