9" HipMaster®

Ventilates hips for roof pitches 3/12 to 12/12. Can be joined with RidgeMaster® Plus ridge ventilation. Patented triple baffle system engineered to keep blowing rain and snow from entering. Internal filter blocks out insects, leaves and pine needles. Low-profile design is unobtrusive, but also crushproof with nailing supports and structural ribs; withstands falling tree branches, hammer blows and resists cracking. Available 9" or 11" widths.
