Use the CRL Plate Glass Dolly to move glass easier, and faster from upright storage. The 1-1/2" (38 mm) center groove is wide enough for even thick laminated panels. The balanced arrangement of casters allows you to turn-on-a-dime so you can use it in restricted spaces. Felt pads on either end cushion loads during movement. All wheels and casters are made of tough phenolic plastic and roll on ball bearings. An ideal dolly for moving insulating glass units, safety glass, mirrors, plastics, or marble. Dollies have a capacity of 350 lbs. (159 kg).
