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.
1.Daylight Opening: Exact size of finished opening.
2.Sideroom: required distance from the door opening to a wall or any obstruction. Refer To Sideroom Requirements.
3.Headroom: required distance from top of door opening to the ceiling or underside of joists. Refer To Headroom Chart.
4.Backroom: required distance from door opening header to the furthest back point to which the door track or operator unit, and their brackets, will extend. Refer to Backroom Chart.
Verify the operating zone dimensions.
1 - Exact size of finished daylight opening. Do you have the correct door size?
2 - Sideroom requirements for track and spring shaft. (Refer to sideroom chart)
3 - Headroom requirements. (Refer to headroom chart for standard lift track)
4 - Backroom (depth into room) Manual lift = Door height plus 18” ; Operators = Door height plus 48” (Standard Lift)
5 - Jambs must be plumb and solidly attached to the building. Floor must be level or exact gradeline established before you start.
Shipping tags show important information, door size, track size and type, spring size and hardware type. Verify that all material is present and correct before attempting installation.
