65 Slant Back Vent web

65 Slant Back Vent

A compact, square-top static roof vent that’s built for the long-term protection of asphalt shingle roof systems. Engineered for durability, installer confidence, and dependable ventilation performance. The 65 slant back incorporates structural ribs that enhance rigidity and strength, reinforcing structural integrity and providing peace of mind.

Benefits

The 65 Slant Back Vent features a high Net Free Venting Area of 65 square inches, requiring fewer roof penetrations. Suitable for any pitch from 3/12 to 12/12, its four side crickets shed water around the throat of the vent, making it virtually leak proof. The 65 Slant Back Vent is exceptionally durable, as it retains its shape and maintains performance as a result of structural reinforcement. Corrosion-resistant and built for long-term exposure. The 65 Slant Back Vent is available in three colors: black, brown, and weatherwood.
