Products / B-144 Dome Static Vents

B-144 is Air Vent's round dome static roof vent in two versions: a gray plastic dome and a heavy-duty galvanized steel dome in mill, black, brown and weatherwood. The 2026 ventilation catalog prints a 24 x 24 in. flashing and 144 square inches of net free area per vent for both, a 14 in. round opening for the plastic dome, and a rust-free screen against animals for the metal dome. 25 in. plastic and metal replacement domes are listed alongside, and the catalog prints a limited lifetime warranty for both versions.
