STACK PACK™ Dolly : FLEX (FS1701) Roll your STACK PACK™ setup to, from, and around your garage, workshop, or jobsite with the FLEX STACK PACK™ Dolly. Built with a 250-pound load capacity for tools, materials, and accessories, the dolly features 360-degree 4-inch casters designed to smoothly glide while being tough enough to handle jobsites. Quick-connect latches deliver fast and effortless interlocking connectivity so you can quickly stack and unstack toolboxes, while foot brakes lock your stacked load in place. Tether points secure cargo for transport or long-term storage. A folding storage hook allows the dolly to hang from STACK PACK™ Rack Rail attachments (FS1603 and FS1604-2, sold separately) when not in use, and side grab handles allow for easy maneuverability.
