The Polecat System is a versatile Tinker-Toy-Like system for constructing lighting and background supports on location or in the studio. I guess I should have explained that in the ad. Back in the '70's and '80's every studio had something like PoleCats hanging around. They can support backgrounds, seamless, booms, fresnels, etc. They are extremely heavy and you can keep adding extensions until the pole reaches the ceiling.
