Cobra CGRV10520 Gun Nailable Ridge Vent 10.5x20

Product Description

The COBRA CGRV10520 is a gun-nailable ridge vent designed for sloped residential roofing applications. It features a low-profile fiber mat construction measuring 10.5 x 20 inches with a 3/4-inch thickness, delivering a net free area of 14.1 square inches per linear foot. The fiber mat allows maximum passive airflow along the ridge while blocking water intrusion and insect entry. There is no fabric overwrap or filter media to clog or degrade over time. The vent is flexible and easy to handle during installation and comes with a 40-year limited warranty. Each roll is sold as a single unit and includes 2-1/2-inch roofing nails for gun nailing.

This ridge vent is suited for residential sloped roof installations where a low-profile exhaust vent is required. It conforms to roof pitches ranging from 2/12 to 20/12, making it adaptable across a wide range of residential roof geometries. The gun-nailable design speeds up installation for roofing crews using pneumatic nail guns. The CGRV10520 is the gun-nail variant of the COBRA ridge vent line; a hand-nail version (GAFCB10520) is also available with a net free area of 16.9 square inches per linear foot.

Installation Notes

Installation is performed by licensed roofing contractors following local building code requirements for attic ventilation and roof assembly. Ensure the continuous ridge slot is cut to the manufacturer-specified width before laying and fastening the vent. Use a pneumatic nail gun with the included 2-1/2-inch roofing nails; do not hand-nail this gun-nail variant, as the fiber mat is engineered for the compressed-nail seating pattern. Inspect the installed vent for proper seating and overlap at joints before applying cap shingles.
