The light- and medium-duty models join the current heavy-duty model, making three different models of drywall carts available to use on your next job site. All carts feature a removable handle for easy storage and handling. Units are shipped knocked-down and require only one tool for assembly. The light-duty model has a capacity of 2,500 pounds, while the medium- and heavy-duty models offer a capacity of 3,000 pounds. Rigid, swivel and locking-swivel 8-inch casters are available in a variety of combinations (plastic and steel hubs).
