The VLSC 400 powered vacuum lift installs windows, window units and windshields regardless of shape, size, curvature and method of attachment to the vehicle. It manipulates, removes and installs side windows, window units and windshields up to 400 lbs., resulting in reduced manpower, requiring one person instead of three; less chance of ergonomic injury, workers compensation claims and absenteeism; and reduced chance of glass and vehicle damage.
