Snap-Loc E-Track Dolly Push Bar transforms your dolly into a push cart platform truck for improved control and easier movement over ramps, curbs, steps, and rough surfaces. Built-in connectors allow quick attachment, and using two push bars or interconnecting units creates a stable platform for moving larger items like lumber and pipe. Made from heavy-duty 1-1/4” industrial steel with a powder-coated finish, this durable design quickly assembles, disassembles, and stores compactly.
