The Kessler Shuttle Dolly Motor Mount Kit allows you to connect a Kessler Second Shooter Plus or CineDrive motion control unit to the Kessler Shuttle Dolly to create a powerful motorized dolly solution. In this kit we send the mounting bracket & 24-foot belt. Please note that dolly runs longer than 24 feet are not supported with this kit. If you don’t already have a rail system for your Shuttle Dolly, the Kessler Kwik Rail Kit can be rented separately.
