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.

I ordered this plenum box when installing a panel ceiling to upgrade the look and fitment of the exisiting plenum box. Flaw number one is the oval duct connection. Standard duct connections are round so why this manufacturer choose an oval design doesn't make much send. Because it was the "look" I w3anted, I ordered an oval to round elbow at the additional cost of nearly $90. Install was fairly simple once the duct work was connected however, the box measure 11' 15/16". Given that a standard 2X12 joist is 11' 1/2" and then drywall is 5/8" that comes to a total of 11' 7/8" leaving the mouth hanging about 1/8 to 1/4 inch proud of the drywall. No big deal as I just trimmed out the opening with 1X2 material so the vent cover would lay flush. This would not be a problem on a second story or opening to an attic but this plenum was installed on a 1st floor which caused some issue. I am assuming since these plenum boxes are mass produced in China as printed on the label there may be a manufacturing issue? But it would be nice if they would convert the duct attachment to a round instead of an oval and reduce the height of the plenum to allow for easier install fitment for the user.
