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