Perfect arches are those where the radius of the circle is constant at all points (half of a circle). Perfect arches do not require a template.
You can mount an Arch over standard shades with no light gap between the arch and standard shade portions of the window. The arch portion is fixed while the standard shade operates normally.
Remember the following information to order a Perfect Arch:
- Radius of the arch (from the bottom center to any outer edge) must be constant at all points.
- Order by the total width of the bottom of the arch.
- Minimum Width - 6". Maximum Width - 84".
- Arch is fixed and will not move.
