Our line of Fold-up lifts are uniquely designed and are rather compact. Like our other products, again, only quality components are used. These lifts are constructed of structural marine grade aluminum and stainless steel, are fully Heli-arc welded, and have a powder- coated finish. Nearly all the parts are CNC machined adding to the lifts quality. The unit consists of an outer aluminum frame that attaches to the surrounding rough opening. The Plasma TV attaches to a swing-arm that is operated by a gear driven cam-lever system that is totally counter- balanced. The unit operates very quietly, and swings down for viewing and can be adjusted to swing back an additional 18 degrees for a proper viewing angle in any installation. When stowing the device, the swing-arm returns to the closed position, and activates a mechanically controlled safety locking bolt to secure the swing-arm in it's position. The lift is activated by a relay interface and simply requires a 12vdc (Or other voltage) power input to deploy the lift.  The lifts are light weight (42" model weighs only 85lbs.) yet built to last. You can expect years of quiet and trouble free service from this product.
