A shoulder flat arch is a simple yet elegant rounding of the corners of an opening. This arch is especially popular with low header heights and larger openings when the rise of the other arch styles is impractical. With the shoulder flat arch, you keep your original header height with the added benefit of an elegant radius corner.
| Quantity |
Every order includes a pair of shoulder arches. One for the right side and one for the left side of your opening. |
| Material |
Medium Density Fiberboard (MDF) |
| Thickness (in.) |
3/4” – 1" (depending on width) |
| Depth (in.) |
1” to 5 ½”. Any depth over 5½” will be made as a split (a 2¾” arch for both the front and back of the opening). Lastly, a shoulder flat arch depth is limited to 18”. Anything greater than 18" is considered a barrel vault. |
When deciding what size radius corner to use, we always recommend starting with personal preference. However, the rule of thumb is that the wider the opening, the larger the radius corner. For example, an 8 inch radius corner on a 3 foot opening would be more in line that on a 12 foot opening. An easy way to decide, is to mark down from the header on the stud, and mark the header out from the stud your desired radius corner. Then stand back and see if you like it.
Every shoulder flat arch kit comes with tailored installation instructions to your specifications. It really is as simple as measuring and marking your header, marking down from the header, and then aligning and fastening each shoulder flat arch corner to the stud and header.
Drywalling a shoulder flat arch is comprised of measuring the curvature of the arch, cutting the drywall to the curvature and depth, forming and fastening in place. You can also watch our "How to Drywall an Archway" YouTube video.
