SKU RBV-4-C2-SM-rib
The RBV-4-C2-SM-Rib is a premium 4 in. round-back static roof vent engineered specifically for metal roofs. This is done by featuring a 11 in. x 12 in. sub-base that is fabricated to the profile of the SM-Rib, Tuff Rib, Panel-Loc Plus, AG-Rib, and Master Rib exposed fastener metal roof designs. Having the roof vents base match the shape of the SM-Rib roof ensures a watertight, professional fit. Optimal Airflow: A 2 in. tall collar provides critical clearance between the roofline and the internal louvers, maximizing exhaust efficiency. Capacity: With 12 square inches of Net Free Area (NFA), a single vent effectively exhausts up to 50 sq. ft. of attic space (based on the IBC 1/300 rule). Strategic Placement: Designed for roof pitches of 2/12 or greater. For maximum performance, you may install the roof vent down to 4 feet maximum from the ridge cap to capture and release the hottest air and moisture. Weather-Ready Design: Spun from a single piece of heavy-duty, corrosion-resistant aluminum, the aerodynamic lid provides superior structural strength against high winds and harsh weather. Pest & Debris Shield: Precision-engineered internal louvers prevent rain and snow intrusion while keeping birds, insects, and wildlife out of your attic. Lifetime Build: All-aluminum construction ensures the unit will remain rust-free for the life of the roof.
