The New "Large"
- Currently On Backorder -
I'm sorry but the Large Vent Caps are currently on backorder. With increased transport costs and tariff's, I'm only able - as a one man, self-funded operation - to order in limited quantities. More are on the way, but to ensure you get some, go ahead and order now. When available, orders will be filled on a first come, first served basis. Thank you for your support and patience! Trust me, they're worth the wait. . .
A larger, square version of our original Vent Cap, the Large features the same heavy duty injection molded, polypropylene construction with machined aluminum cord locks and full one year warranty. The 16.5” square size (inside the gasket, actual product larger), can easily cover a 14” air duct vent, with over an inch to spare! They're perfect to seal HVAC returns in bedrooms, and large square air duct vents.
The Large can also be attached with the Pole RAT™ (remote attachment tool). Cut down on ladder use (for SO many reasons), quit moving furniture. . . - all while using less $40/roll duct mask. There isn't an easier, or more reliable, way to seal HVAC vents.
