The Mega Airwall Hanger 4" is 500 pound load rated. The Mega-Airwall Hanger will fit a wide variety of air wall tracks. The Mega Airwall Hanger engages the airwall track the full length of the hanger giving a total of 8 inches of metal to metal connection. The Mega-Airwall Hanger panels move outward and apart at the top to engage the airwall track. The tops of the hanger panels have a continious lip that rests on the load bearing portion of the airwall track. These panels lock onto the track without damage to the track. Turning the center knurled wheel assembly easily expands the panels to lock the Mega Airwall Hanger into the track structure. The 1/8" hair pin safety is then applied to the wheel to lock the wheel rotation. The Mega Airwall Hangers have a center opening above the 1.9 inch diameter round pipe like section to clamp a light fixture, coupler, or attach slings. The Mega Airwall Hanger will fit into slot sizes from 0.8" to 2.25" wide and depths from 0.3" to 3".
