The PortaRail Precision Collapsible Speed Rail Kit from RigWheels includes four 19" sections, two threaded connectors, and eight rubber end caps. Constructed from 6061 aluminum for rigidity and machined to a tolerance of 0.001", these rails provide precision camera movement. The four 19" sections can be screwed together via the included connectors to form two 38" long rails for the PortaRail collapsible dolly/slider rail system (not included). These rods can also be used with other suspended or ground-rail systems that work with an outer diameter of 1.65" (41.9mm).
