  When you have heavy glass to lift and need cord-free movement we have the equipment to help you get the job done. The CRL Powr-Grip P11004DC Powr-Grip Single Channel Vacuum Lifting Frame features four 10 inch (254 millimeters) curved rubber cups, mounted on a steel channel which, when attached to the glass, measures 10 x 49 inches (254 x 1245 millimeters).
  
  Each P11004DC carries its own vacuum pump and controls; applies in 6 sec. and releases in 12; weighs only 70 pounds (32 kilograms) ready to work and carries a safe work load rating of 600 pounds (270 kilograms). Restrictions at the cups minimize the chance of load loss if the glass breaks across one cup. Stocked in 12-Volt DC power, the units are also available in optional 115-Volt AC power. The P11004DC comes with a heavy-duty aluminum lift bar which gives the unit 180º of edgewise rotation with positive locking in three positions; 90º of tilt, vertical to flat; and automatic latching in the upright position.
