This is a universal product and can be used with any other “speed-rail” type slider or dolly with a similar OD. The outside diameter is 1.65″ (41.9mm) which corresponds to the OD of 1-1/4″ speed rail.
RigWheels PortaRail is the original Collapsible Speed Rail system. First introduced in 2014 it is the strongest and most accurate collapsable rail that we have seen on the market. Constructed from high-grade 6061 aluminum for rigidity and machined to a tolerance of .001″, sections of the track connect seamlessly via threaded connectors (you will not notice a “bump” when rolling over them).
The removable connectors serve several important purposes.
1) If threads are damaged from mishandling, they can be replaced.
2) They allow the tubes to remain lightweight without compromising strength.
3) They allow other types of adapters and connections to be screwed into the tubes.
Sections are 40″ (1 meter) long. The 6061 aluminum is much stronger than the architectural aluminum that is sometimes used for similar applications. The stronger material provides much more rigidity which means a more solid system with very little flex. At 80″ the camera slider rails have less than 1/8″ of flex with a 40-pound load placed at the center. Each piece goes through a 6 step process to make them straight enough and round enough for precision camera movement.
We have a custom pelican case and soft case available which holds 6, 40″ tubes. It is a high-quality professional case but it does add a lot of cost to a set of rails.
