Arches are made with the same profiles of any of the standard trim pieces in our online catalog. You will be asked for a trim style (profile) when you place your order. Standard arches are typically applied to a flat, vertical surface - around windows, and archways, and even to create a circle by combining two half arches. Inside and outside barrel arches are not typical and are explained below.
Please Note: If your arch is not a true circular arch with a radius, these would be considered specialty arches and would require you to provide a pattern.
Your arch will match the measured dimensions you provide to us, so please CHECK ALL MEASUREMENTS before ordering.
