Keystone Arch Trim
The keystone arch trim is a decorative architectural detail placed at the apex center of arched passages or windows to recreate the iconic classical keystone appearance. It serves as an aesthetic focal point in both interior spaces and exterior facades. Significantly lighter than traditional stone or cast concrete keystones, the high-density polyurethane construction exerts minimal static load on the supporting structure. It boasts complete resistance to moisture, water intrusion, and impacts, ensuring it will not crack, chip, or decay over time. Precision molded for clear relief definition, it accepts all standard paints easily.
