3 in 1 FlexFit Vent

3-in-1 FlexFit™ Vent

The most innovative, field-adjustable ridge vent on the market converts from 12 inches to 10 inches or 9 inches ridge vent by simply scoring the groove on the top of the vent. Made from durable, no-break polypropylene, it won’t rust or dent, and closed external baffles make it less likely to collect debris, resulting in diminished airflow.

Benefits

The patented FlexFit 3-in-1 Ridge Vent is suitable for any roof pitch from 2/12 to 12/12 and provides a generous 84 square inches of Net Free Venting Area per piece. A vital piece for any shingled roof, the FlexFit 3-in-1 Ridge Vent helps attics breathe to keep cool and dry, reducing utility costs, preventing mold and mildew, extending shingle and roof-deck life, reducing air conditioning maintenance costs, and eliminating damaging ice dams in winter months.
