Products / Maxx Air SBV Series Slant Back Static Vents

Maxx Air's slant-back static roof vents, sold in multi-packs for roofs up to 8/12 pitch with a built-in metal mesh screen against birds and insects: the galvanized steel SBV 40 GV at 40 sq. in. of net free area per vent, the galvanized steel SBV 603 at 51 sq. in., and the low-profile SBV 61 at 61 sq. in. The SBV 61 listing describes it as galvanized steel in one line and as UV-inhibited polypropylene in another, and offers it only as polypropylene; the two descriptions disagree.
