DecraTek® has developed a complete Arched Door System so simple that it is like a kit that only needs nails to be assembled. However, if you work on any part of the System yourself, please thoroughly read the text in this section. A high level of attention to detail is needed due to the hundreds of different radii and miters. In order to ensure a consistent look throughout a home, the arch must begin and crest at the same location for a 2’4” as it does for a 5’0” pair. Therefore, every door width and every rise has a different radius that requires a unique miter. It can seem confusing, but DecraTek® does the hard part to make it easy.
