A Split Unit Insta Arch® is capable of taking an opening larger than 96" and creating the same Arch affect. The curvature of the corners depends on the size of the arch installed. For a slight curve, smaller arches such as a 16" through 48" arch are recommended. For a more defined curvature, 60" through 96" Insta Arch® are highly recommended.
Step 5
