Measure the existing door width at the opening or frame from the outermost edges on each side near the top of the opening.
-
Divide that overall width measurement in half to find the center of the Opening.
-
Clearly mark the center at the top of the door frame or its header.

-
Place the G2 Door roll Header Assembly across a safe and level work surface, and rotate the roll assembly frame so that the Header Bracket Mounting flanges are facing upward.
-
Measure the total width of the whole roll assembly from outermost edge of one Header Bracket’s Mounting flange to the outermost edge of the opposite side.
-
Divide that number by 2.
-
Measure to each side of the center mark of the Opening in step 1. Mark a vertical line at these locations. This is where the outer edges of the Header Bracket’s Mounting flanges will be.

-
Lay one of the Vertical Track Assemblies on your work surface.
-
Measure its overall length. Do not include the Transition piece in your measurement.
-
Add ¼” to this number and take note. This is the height dimension needed to mark the location of the Bottom edge of the Header Mounting Brackets.
-
With this number, add a horizontal line on each side of the opening that intersects the previously drawn vertical line marking the overall width of the roll assembly.
