Arch-It, Start Making Perfect Arches in Minutes, Not Hours
Eyebrow Arches are as Easy as 1-2-3!
Note: For jambs larger than 3-1/2 inches, DO NOT SPLIT ARCH until you've done steps 1 and 2.
1.
Use a square to mark a line a short distance from one end of the eyebrow. Set your circular saw to the proper angle for the size of eyebrow (see the table at right). Cut along the line, making sure your saw blade is tilted inward as shown.
A Few Tips:
Are nail guns OK?
We recommend wood screws. In fact, nailing invalidates the warranty.
Symmetrical:
There's no top or bottom — install without worrying which way is up.
Jamb wider than 3-1/2"?
First, follow steps 1 and 2. Then, using a sharp drywall knife, scribe the groove on the back of the arch until the arch separates. Rip a piece of scrap lumber to 7/8 in. to fit the gap between the arch and the header. Place one side of arch in the opening, making sure that both sides measure down equally, then screw in place. From the bottom of the arch, square a line to the other side, then line up the second half and screw it in place.
Mudding, nailers:
You can plaster directly onto the arch. Simply drywall over the wall side of the arch, zip it, attach a corner bead and mud it.
Headers:
Remember, arches aren't designed to be structural support; only to be support for drywall.
2.
Measure across the width of the rough opening, then transfer that measurement to the arch and make another square line. Using the same degree setting, cut along that line.
3.
Slide the arch into the opening. Make sure that both ends measure down equally on both sides, then screw in place.
