Half round moulding can be used in crown applications, and the possibilities don't stop there. It can also enrich cabinets, recessed shelves, furniture and more. Architectural Depot is your source for versatile urethane moulding products. We offer mouldings ranging from ornate to minimal in form. Whether you require something designed for use in a specific application, or something more flexible, we have what you need to get the job done. This half round moulding measures 12 feet in length. It is part of our urethane millwork selection. Rigid, high-density urethane conveys the classic beauty of materials like wood or plaster, but with modern ease of installation and moisture-resistance.
