Lomanco 700 Series Roof Louvers are built with three outward and upward discharging side vents to prevent unsightly roof streaking that is so common with ordinary roof louvers. This exclusive Lomanco design also prevents the problem of bird and animal infiltration while providing maximum attic exhaust air flow and weather protection.
Measuring 16-5/8 x 22-3/8 x 6 in, the 770 is a slightly larger version of the original 750 Slant Back Vent. The embossed aluminum finish provides added strength and extended paint life while blending closely with shingles.
Lomanco® Static Roof Vents are exhaust vents by design. Each vent's unique design offers maximum weather protection.
