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.
This urethane keystone features a recessed panel enriched with fine moulding details that emphasize its tapered form. The keystone is made to accommodate the profile of 9" and 10" crossheads with bottom trim details. The keystone attaches easily for a quick enhancement that adds character to the crosshead. The recessed keystone is precision molded in rigid-high-density polyurethane foam. Like our urethane crossheads, urethane keystones are non-porous and withstand the effects of moisture. As with many architectural elements, the functional keystone gained prominence for its decorative value. Today, the decorative keystone brings with it a sense of prominence, detail and traditional style.
