Arch Trim FAQ'S

Why aren't my curved vinyl windows true half rounds?
Vinyl window manufacturers have dufficulty in providing precise curved shapes. We have found many that are not made with a true radius. A field template will ensure that the curved trim properly fit your window.

What is the tolerance of curved trim boards fitting to the window?
We manufacture to a one-eighth inch gap between the window and the curved trim. If additional spacing is required, please make a note of this on the order form.

Why aren’t curved trim boards trimmed to the base of the window?
OMC Archtrim purposely leaves the trim extended to facilitate field trimming, allowing the trim to be mitred or butt jointed to straight trim boards. Legs are left 6-8 inches longer than the base of the window.
