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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07NF8LBBM | | Batteries Required? | No | | Batteries included? | No | | Brand | BUILDMART | | Colour | White | | Customer Reviews | 4.4 4.4 out of 5 stars (85) | | Date First Available | 6 Feb. 2019 | | Finish types | Finished | | Guaranteed software updates until | unknown | | Included Components | Screws | | Item Weight | 1.97 kg | | Item model number | 48x2S | | Manufacturer | Texas Buildmart | | Material | Aluminum | | Part Number | 48x2S | | Power and Plug Description | AC, solar_powered | | Product Dimensions | 124.46 x 12.7 x 5.08 cm; 1.97 kg | | Shape | Rectangle | | Special features | Easy to Install | | Specific Uses | Commercial/Residential | | Switch Installation Type | Screw-In | ## Images ![48" 2 Slot Linear Slot Diffuser - Image 1](https://m.media-amazon.com/images/I/51-wDggImsL.jpg) ![48" 2 Slot Linear Slot Diffuser - Image 2](https://m.media-amazon.com/images/I/61ecPTKw7pL.jpg) ![48" 2 Slot Linear Slot Diffuser - Image 3](https://m.media-amazon.com/images/I/51y-55v6lqL.jpg) ![48" 2 Slot Linear Slot Diffuser - Image 4](https://m.media-amazon.com/images/I/81R5nP0MM9L.jpg) ![48" 2 Slot Linear Slot Diffuser - Image 5](https://m.media-amazon.com/images/I/61UtD2TbGWL.jpg) ## Questions & Answers **Q: What does a Linear Slot Diffuser do?
