95984 Unfiltered Ridge Vent, 12 in L, Polypropylene, Black

Designed with external baffles which maximize airflow across the underside of roof sheathing, the CertainTeed® ridge vent works year round to efficiently and effectively ventilate an attic space. Less than an inch in height and molded from high-impact copolymer, it's slim profile blends for visual appeal while permitting shingle capping over the ridge for a uniform, finished roof aesthetic. CertainTeed ridge vents, combined with sufficient intake ventilation such as soffit vents or CertainTeed intake vent, are the most efficient and effective systems you can install.
