## Description

Texas Buildmart offers High Quality Linear Slot Diffusers. This model shoots a 180-degree spread with 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 product can be used as a supply and as a return register vent cover for ceilings, walls, and floors but looks like a Modern Contemporary looking fixture.

Review: Unit arrived with a bend frame. Maybe 3mm pushed in. Then we tried to open the air vents and the inner parts fell out immediately. So we thought just have it open in the slot , but the wind noise is just too loud. As a European, you can't compare anything here. People will accept almost anything for a high price thinking it's good stuff.
