ROLL VENT 20'/ROLL QUARRIX

Made of corrosion-free, laminated high-density polyethylene corrugated plastic with a thin spun bound non-absorbent polypropylene membrane bonded to it which does not allow direct water or weather entry. "One-Pass" nail attachment allows for quick installment (nails included in specified items only). Draws fresh air from soffit vents and continually releases hot, moist air through the ridge line. Low profile design enables the ridge vent to virtually disappear into the roofline. 5/8" thickness. 12.7 sq. ins. of net free area. 1-3/4" nails included with specified items.
