Mitered corners bring you perfectly angled and finished corners every time with no complicated cuts required. This mitered inside corner is designed for use with the E-Vent System's Crown Dentil profile (EV404). It features fine moulding complimenting crisp and bold dentil details. The mitered inside corner is precision molded in urethane. The closed cell structure of urethane blocks the absorption of moisture for high performance in exterior applications. Urethane E-Vent components resist warping, cracking, peeling, mildew and decay while maintaining the classic appearance that many desire. Urethane components are also pre-primed and ready for painting.
