Vents for Crawlspace

Turnbuckle Adjustment Lets a Single Vortex™ Vent Fit Walls of Different Thicknesses

Welcome to the future of foundation ventilation - Vortex™ telescopic, variable-flow crawl space vents.
Vortex telescopic vents come in two expandable sizes to fit either 5, 6 and 7 inch walls, or 8, 9 and 10 inch walls, both nominal and full. And since the vent's thickness can be adjusted, there's no longer a need to keep dozens of odd-sized vents around.
The revolutionary turnbuckle adjusters on each side of every Vortex vent lets you quickly telescope each vent on the job site to save you time and trouble, while reducing inventory and storage headaches.
Plus, Vortex variable flow controls let homeowners manually adjust air flow as needed.
