- *This is a design and utility patent pending product* We make sizes from 12" to 72" linear slot diffuser ac vent covers for the modern day home
- We have over 70 standard vent cover sizes to replace your traditional looking grills. We also have over 40 linear slot diffuser sizes with their matching plenum box. All models are in stock ready to ship in both white and black colors – Our models are also paintable.
- All vent cover sizes can be used as both supply and return grilles. Currently our decorative air vent covers are non-filtered models. This will work perfectly if you have your filter in the machine.
- A standard linear slot diffuser is a modern looking decorative air vent cover that fits on a traditional air exit and replaces the traditional looking grills. They have a beautiful linear slot diffuser; they are easy to replace since it is retrofit to the traditional vent cover sizes. Enjoy the incredible looks, the durability since it is 100% aluminum, and they are also very easy to clean. A linear slot diffuser is a linear air exit or vent cover with a long linear look that you usually find in hotels and modern houses. The standard linear slot diffusers and the linear slot diffusers can both be used for remodels and new construction.
- The size that you need to know to buy this vent cover, or any other vent cover is by measuring the air duct opening (the plenum box opening) and not the face size or the vent cover. We recommend you remove the old air vent cover and measure the size of the air duct opening. You do not need to take into consideration the face size of the vent cover. The important measurement is the interior duct opening size. Example: A traditional vent cover size can have a face size of 14x8, and neck of a little less than a 12x6. Your air duct opening should measure 12x6, so you purchase a 12x6. Vent cover dimensions are categorized by the neck and not by the face of the air vent cover.
- The method of installation of our modern air ac vent cover is hidden through the pre-drilled holes inside of the diffuser, which can be accessed by opening the dampers and using a drill with a six-inch extension to screw it into place. Please find attached our instructional videos. This way we avoid having a front drill screw and ruin the esthetics of the product.
