The mitered inside corner is designed for use with the finely molded crown profile (EV570). Molded inside corners give you perfect angles every time. They also cut down on tooling times and costs. This mitered corner is in step with traditional exteriors, but it is crafted in modern urethane, offering a balance between the classic detail and high performance. The mitered corner is precision molded in rigid, high-density urethane. Our urethane products are easy to work with, as they are lightweight. Urethane moulding products are non-porous and moisture resistant, so they will not crack or rot. If you are looking for an alternative to wood, urethane offers a low-maintenance solution.
