Quick Overview
Keystones adorn window trim, entry door systems, crossheads, garage doors and arch casing. These timeless accents offer classic historical and decorative detail. Our lightweight keystones can be installed during new construction or after as a renovation. For use with select crosshead and casing profiles.
The flat keystone is designed for use with the moulding profile FLT162. The keystone installs easily over the flat moulding. As with our versatile mouldings, the flat keystone is precision-molded in urethane, a rigid, high-density material that performs exceptionally well while remaining traditionally beautiful. Due to low moisture absorbency, the flat keystone holds paint well and it is pre-primed. Our extensive trim selection includes keystones designed for use with specific mouldings, as well as completely versatile keystones that can be attached to any surface. The decorative keystone easily improves decor both inside and out, whether you are enhancing a grand exterior entryway or bedroom window.
