Adjust-a-vent wgx series diffuser

Features: Experience the difference! A "true-size" diffuser that utilizes the roominess of its inner cavity to provide maximum airflow. The Adjust-A-Vent diffusers feature dualflow: air supply or air exhaust, true-size inner cavity, snap-in trim ring, 4 wing adjustment screw that fine tunes air flow settings, and is available in 5 sizes. The WGX4S vent is compatible with Primex's Squeeze Elbow accessory. EB4x90. Benefits include secure friction fit in most installations, very quiet during operation, and will not rust or dent. The added security of mounting screws through base flange. The trim ring snaps in place over flange to hide mounting screws. Trim ring removal does not interfere with mounted diffuser.
