The mitered outside corner features the fine moulding details of its crown moulding profile (EV570). The mitered corner results in perfectly mitered angles every time. We are committed to bringing you innovative, beautiful and enduring exterior products, and our selection of E-Vent mouldings and corners is an excellent example. Ventilate and accentuate your roof with the E-Vent eave ventilation system, a system that provides a concealed means to ventilation. E-Vent components are crafted in durable high-density urethane. Urethane has a weight and feel similar to that of pinewood. It is non-porous and highly resistant to the effects of moisture and climate.
