[Proper Sizing First]: Measure your ceiling or sidewall opening at exactly 30" x 12" before purchasing. The visible face measures 31.6" x 13.6", ensuring a perfect fit and a neat finish. [No Movable Parts]: Fixed blades at a 38° angle—no louver, no filter, and no adjustable fins—provide consistent airflow without adjustments or levers. [Not for Floor or Exterior]: Strictly designed for indoor ceiling or sidewall installations. Not suitable for floors or outdoor use. [High-Grade Aluminum]: Made with extruded aluminum AA6063 for strength, durability, and rust-free longevity—an ideal air conditioning vent cover. [Semi-Matte White Finish]: Coated in a high-resistance electrostatic white powder (Laminaire, similar to RAL 9003), ensuring a smooth, scratch-resistant surface that complements any décor. [Lightweight Design]: Prevents sagging or dislodging over time, maintaining a stable, reliable fit. [Reinforced Corners]: Internal reinforcements prevent corner separation, ensuring long-term structural integrity. [ASHRAE Standard]: Manufactured under stringent ASHRAE standards for trusted quality and performance. [Easy Installation]: Pre-drilled screw holes on the cover simplify setup, and included galvanized steel cross-head screws (5/32" x 1 1/2", white head) for wood and drywall ensure a secure, hassle-free installation. [Secure Packaging]: Each return grille is individually packed in a plastic bag with corner protection, arriving damage-free and ready to install.
