Worthington Arches – Installation Instructions & Specifications
html | PDF | Doc
Worthington arches come as a true half round with 3 extensions that can be cut to adjust the arch to line up with the bottom of the window (except for WA-3024 & WA-2000 arches which do not have the extensions). Worthington arches can be installed using galvanized nails or screws and work well with nail guns. Please test to set depth of the nail before installing. Worthington arches larger than 48" are provided in two halves that need to be joined in the center at the top of the window. We recommend using urethane adhesive in the joint to prevent separation.
