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.

NOTE: 2 1/2” OF ADDITIONAL HEADROOM IS REQUIRED FOR SINGLE TROLLEY OPERATOR INSTALLATIONS.
STEP 1. Verify The OPERATING ZONE Dimensions
A - Exact size of finished daylight opening. Do you have the correct door size? B - Sideroom requirements for track and spring shaft. (Refer to sideroom chart) C - Headroom requirements. (Refer to headroom chart)
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.
STEP 2. Shipping tags show important information, door size, track size and type, spring size and hardware type. Verify that all material is present before attempting installation.
