Arch-It arches are specially designed to fit into standard window or door openings. All are 3-1/2 in. wide by 1-1/4 in. thick. For all interior or exterior openings that can be enhanced by an arch, there's no quicker, easier or more attractive way to get the job done than with Arch-It.
Best of all, Arch-It saves significant time — and money — compared to the old-fashioned plywood-and-block method.
