Python™ 150 Round Vent

Brand: Marco Industries

With 150 square inches of Net Free Venting Area, the Python 150 Round Vent is ideal for larger roofs. It requires only a third of the roof penetrations of typical 50 NFVA vents, saving time and money. 

Made of high-impact polypropylene with heat stabilizers and UV inhibitors throughout, it will not rust or dent.

The Python 150 Round Vent is suitable for any pitch from 2/12 to 16/12. Available in black, brown, and weatherwood, it can compliment any of today’s shingle color choices. 

The Python 150 Round Vent helps attics breath to keep cool and dry, reducing utility costs, preventing mold and mildew, extending shingle and roof-deck life, reducing air conditioning maintenance costs, and eliminating damaging ice dams in winter months.
