I utilized this on a film. It worked effectively. It's a standard skater type dolly with 24ft of aluminum track (6 pieces which are 4 foot each) that is keepinged together with a bracing system. I suggest mounting whichever fast release block you utilize on the dolly. It will make your life a lot easier. Overall, this gear is rather great. Someone made it for me years back. I just utilized it once in a field. I am including a large Tuxedo brand padded soft case, which will certainly make it a LOT simpler to lug around to area. The padded case alone cost me a fortune. Please do not bargain, I'm currently having a cardiac arrest considering just how much money I'm losing on it. I am in New London, PA.
