Allows you to rig a single or double vertical speedrail from any mitchell base to enable suspension arm mounting from any Mitchell base as found on many dollies, cranes, tripods etc… Using double vertical speedrails prevent any rotation of the suspension arm on the speedrail and results in a stiffer stronger setup. We offer our modular speedrail starters in both common speedrail sizes.
Just add one or two of our “Modular Speedrail starters” in the size speedrail you require.
Mitchell collar and castle nut are INCLUDED to allow you to mount to any mitchell base.
**Modular speedrail starters NOT included. **
