Insulated 12 Plenum Box for Linear Slot Diffuser

Choose from over 70 sizes of modern AC vent covers, ranging from 6x4 to 30x24, to replace your traditional grilles. Additionally, we offer linear diffusers in 1, 2, and 3 slots.

Texas Buildmart originated 10 years ago from Skuadra Construction, where we revamped the standard linear slot diffuser for residential use. Our vent covers are designed, tested, and patented for both design and functionality. Crafted from 100% aluminum to prevent corrosion, our covers are powder-coated with electrostatic paint for a smooth finish that is easy to clean. An essential home décor accent for any beautiful home.

Visit our store to explore our range of modern AC vent covers, including single, double, and triple slot linear diffusers, as well as plenums.

Distinguishing between a modern AC vent cover and a linear slot diffuser, the former is boxy, designed for standard vent sizes, and easy to replace, while the latter boasts a sleek, linear look ideal for new builds and remodels.

Linear slot diffusers serve as the "face" of a vent, distributing air throughout a home or building. Aesthetically pleasing, they provide a modern touch to any room. Standard air vent cover sizes can vary from 6x4 to 30x24, with sizes like 10x6 and 12x6 being commonly found in homes.

For installation, remove your old AC vent cover, measure your vent hole, open the blades, and drill screws to secure the new vent in place.

Our aluminum vent covers are seamless, rust-proof, and durable, providing a sleek and stylish update for your space. Whether for ceilings, walls, floors, or as return air vent covers, our products offer a modern aesthetic.

The linear slot diffusers are recommended for new builds, with HVAC contractors advising on required airflow per room. Vent cover sizes are determined by measuring the air duct opening, not the face size, ensuring a proper fit.

Installation is simple, with pre-drilled holes and hidden mounting methods for a clean finish. Watch our instructional videos for guidance.
