9" RidgeMaster® Plus
A patented added-pitch design reduces the visibility of the vent opening, letting the shingle profile take center stage. The patented internal baffle keeps blowing snow and rain from entering, while an internal filter blocks out insects, leaves and pine needles.
Designed for roof pitches from 3/12 to 12/12, the Ridge Master Plus easily adapts to a peak vent or flash vent. Nailing supports and structural ribs make the Ridge Master Plus crushproof, to withstand falling tree branches and hammer blows, and it resists cracking. Self-aligning, interlocking ends make it easy to install correctly. Built-in end caps adjust to the roof pitch while the ship-lap design allows for expansion and contraction as temperatures change.
