A telescoping device similar to an extra-large “C-Stand,” except this one is on wheels.  Like a C-Stand, it is used for a wide variety of jobs and tasks, but its primary design and function is to support Grip Equipment.  When used in pairs, their most frequent use is in supporting (aluminum) “Frames” for “Silks” or “Nets” or “Solids.”  With its “Tri-pod-like” base legs fully extended (and with permanent heavy duty wheels attached), the High Roller is one of the most essential tools on Set.  Once a “rig” has been built, it’s relatively easy to move about and adjust as needed to meet the needs of the Camera.
