Imagine, one cart that adjusts to meet all of your needs! Adjusting to multiple heights is as simple as resetting four screws. Open, roomy shelves provide ample storage space. Features 14-gauge uprights, 20-gauge die pressed shelves and 4" casters (two locking). Powder paint finish, with certain items available in premium colors for an upcharge. Top shelves are arc-welded and reinforced and come complete with a nonslip ribbed rubber mat. "E" models include a UL and C-UL listed, two-outlet electrical assembly with a 20' extension cord and cord winder.
