Total Jack Brown 6in.

Roof jacks are used to prevent rain, snow and debris from entering a home through attic ventilation and vent pipes that exhaust kitchen and bath fans. The galvanized steel construction of a traditional roof jack provides durability, while the vent cap keeps out water. The traditional roof jack and the Total JACK® from DOT Metal Products both share the same purpose: to keep water from entering a home by protecting any pipe penetration through a roof. They also come in the same general diameters and finishes. However, the most exciting advantage of the Total JACK® is its adjustable cap and turbine base that give it the ability to cover nearly all pitches with one item instead of several. Contractors no longer have to second-guess the true pitch of a roof, or lose time and money when incorrect roof jacks are delivered to the job site.
