Properly Venting
a Roof is the 1st Step in Prolonging It
These box vents are designed to fit any roof pitch. To provide
for maximum ventilation, instaling one vent for every 52 square
feet of attic floor is recommended. It provides 50 square
inches of net free vent area. Made of durable, scratch- and
dent-resistant polypropylene, these vents are offered in colors
to match most standard roofs.
