The Dana Dolly Portable Dolly System with original style track ends is a heavy duty camera dolly platform that rides on 16 custom modified soft polyurethane wheels that resist flat spotting and use ABEC-7 rated precision bearings providing you with extremely smooth dolly shots. This kit is complete with 75, 100, and 150mm bowl adapters, and comes in a custom flight case. The wheel trucks swivel, allowing the dolly to ride on available straight or curved track. The dolly includes two original style track ends, which accept inch and a quarter pipe (standard speed rail), and fit into standard Junior stand receivers. A center support is included for long track runs or when using heavy cameras.
