## Description

Texas Buildmart offers High Quality Linear Slot Diffusers. This model shoots a 180-degree spread with the option to adjust to one side or the other. They have decorative directional dampers. Modern, crisp, clean lines and architecturally appealing. Solid extruded aluminum profile with welding - Electrostatic Paint. This white linear air vent register can be used as a supply air vent cover for ceilings, walls, and floors. This vent cover was designed to be decorative and not structural. You can use this as a floor vent cover, but it is not designed to support weight, adding any type of weight is not recommended. This vent can be used as a return air vent cover as well. This register is not only a vent cover, but it looks like a Modern Contemporary looking fixture. If our Modern AC Vent Cover is used as a Return air vent cover, please make sure the air vent cover is placed in the full open position or remove the directional dampers

Review: We're remodeling our Master Bathroom right now, and as part of that refresh, I wanted to replace the ugly old HVAC vent that was not even centered on the wall with this long, sleek one. The only drawback is that I expected it to be a bit quieter. Installation was easy w.r.t. the product itself. (Installing the plenum box was a bear because of things back in my walls/ceiling I didn't know about until I cut into them, but that's not the product's fault!) These are expensive, but well-made, and definitely bring a more modern and functional high-end aesthetic to either a new build or a remodel.
Review: Excellent quality and quick delivery
