Mitered outside and inside corners result in perfectly finished and angled corners every time. Cut down on tooling times with pre-formed corners. They add to the innovative qualities of the E-Vent eave ventilation system. This mitered outside corner (EV580) features the bold moulding details and prominent projection of the Massive Crown profile. The Massive Crown mitered outside corner is traditional in appearance and modern in construction, as it is molded in high-performance urethane. Rigid, high-density polyurethane foam becomes an excellent medium for the crafting of exterior trim, as it will not warp, crack, stain, decay or offer a food source to insects.
