Dolly Parton Approved. Not really, but the Portable Dolly System Rental Kit from Dana Dolly can cascade a hefty 100 pounds of camera gear across any two standard-speed 1.5 to 1.9-inch diameter rails or Schedule 80 aluminum pipes, curved or straight, like the 6-pack Dana Dolly Portable Aluminum Pipe Kit 39-inch. Its 16 custom-modified soft polyurethane wheels use ABEC-7-rated precision bearings and a swivel feature to glide its way through a cool camera shot. These wheels are engineered and custom modified to allow the system to be parked on the rail in 100° F weather for up to an hour without flat spotting.

Design and Mounting. The platform of the dolly is constructed from heavy-duty machined aluminum, and features a standard Mitchell mount with a 2.75" center hole and an elongated key way. You have access to 6 total accessory mounting points with one 3/8" through hole, one 1/4"-20 threaded hole, and one 3/8"-16 threaded hole an either side of the platform.
