The dolly/slider is not part of the bundle and must be purchased separately.
The_10__ PortaRail Traveler Kit_from_RigWheels_includes six 40" sections and six threaded connectors in a Pelican hard case. The 40" sections can be screwed together via the connectors to form two 10' long rails for the PortaRail collapsible dolly/slider rail system (not included). The protective hard case comes with custom foam insert for safe storage and easy transport.
These rails are constructed from 6061 aluminum for rigidity and provide precision camera movement. At 80" the camera slider rails have less than 1/8" of flex with a 40 lb load placed at the center. These rods can also be used with other suspended or ground-rail systems that work with an outer diameter of 1.65" (41.9mm).
