Python™ Weather-Tite™ FlexFit™ 3-in-1 Ridge Vent
This patented design is not only field-adjustable from a 12" to 10" or 9" ridge vent by simply scoring the groove on the top of the vent, it also features a no clog non-wicking modified polyester weather barrier providing a superior Net Free Venting Area while blocking out moisture, pests, and dust.
Using a chalk line, mark 1" on both sides of the ridge (1" beyond ridge pole) as a guide for cutting a slot in the decking.
Cut a slot in the roof ridge using a circular saw with the blade set at a depth to cut through the roof decking only (avoid cutting trusses and rafters).
Center the Python Weather-Tite FlexFit 3-in-1 Ridge Vent over the slot that has been cut in the ridge, ensuring that the ridge vent support pegs sit flat on the roof. To ensure proper alignment along the ridge, run a chalk line down both sides of the ridge.
Using roofing nails provided, install the vent starting from the outer edge moving inward. Properly secure by using the 12" nail holes.
As you install more pieces of the ridge vent, ensure that each piece is joined together using the male/female connectors.
Cut the final piece to a length long enough so that it is flush with the edge of the roof. Ensure that the self-closed end cap is facing out to prevent weather infiltration. (Interlocking feature will not be used on the final piece.)
Install the cap shingles using the nails provided in the “shingle nail line” area for cap shingle installation as indicated on the Python Weather-Tite FlexFit 3-in-1 Ridge Vent. See instructions for field adjustment to 10 inch and 9 inch sizes.
