Mar-flex designed Vortex vents for maximum versatility. These telescopic vents come in two sizes, expanding to fit 5, 6 and 7 inch walls, as well as 8, 9 and 10 inch walls, nominal and full. They are available in three models – thin manual, manual and automatic.

Mar-flex developed Vortex telescopic and variable flow control vents with homeowners – and contractors – in mind. Because Vortex expands from 4.75 to 7 inches and 7.5 to 10 inches, professionals only need to stock two different vents, which means fewer SKU/inventory headaches. And homeowners breathe easier knowing that Vortex vents disburse harmful gases and protect their home from damage caused by moisture.
The solid steel turnbuckle adjusts for maximum versatility, allowing Vortex vents to expand and fit almost any size wall. |
