American Louver Stratus 2x2 ft 3-Cone T-Bar diffusers. The Stratus all plastic diffusers won't corrode or fade and they're indistinguishable from metal when installed. Made of durable, engineered polymers and stainless steel screws, designed to resist rust, corrosion, fading, and to resist mildew. The polymer features a sleek black color, negating the need to paint the diffuser to match your ceiling. The strong design maintains integrity and will not bend or scratch, despite being 50% lighter than its metal competitors.
