Marathon Aluminum Extra Large Capacity Vent 12 Inch

Description

Marathon Extra Large Capacity 12 inch. Vent provides pressure equalization in the roof system and is spun from heavy gauge aluminum with inique cap design that shields against entry of wind-blown rain or snow. It is available in either one-way or two-way options. One-way nitrile rubber valve prevents moisture from re-entering roofing systems while the two-way option lacks a valve which will allow both exhaust and convective movement of air between the breathers.
