In-Vent is a rooftop intake vent that lets in fresh air when traditional soffit vents cannot be used. Ideal for roofers and remodelers who need to add intake ventilation to balance ridge vents but can't access the soffits or overhangs. Available in 4-foot pieces, it gives 7 inches of unobstructed vent area per linear foot. 800.837.8368. www.coravent.com.
