Snap-Loc E-Track Dolly Panel Bar Set transforms your dolly into a panel cart for easier transport of lumber, drywall, pipe, and large materials, while providing leverage to move loads over bumps, ramps, curbs, and steps. Built-in connectors allow quick attachment, and the bars can be configured as dual push bars or used to interconnect carts for moving larger loads. Made from heavy-duty 1-1/4” industrial steel with a powder-coated finish, this durable system assembles, disassembles, and stores compactly.
