Set Out the Footprint

Set out a 29.5 × 98.4 ft footprint and mark 31 frame lines at 3.28 ft centers. The paired arch legs will be inserted directly at these marks.

Installation action

Set both sidewall strings, mark every 3.28 ft frame position, and identify the door end before drilling begins.

Check before continuing

Confirm equal diagonals, straight side lines, the 29.5 ft span, the 98.4 ft length, and 31 matching frame pairs.
