This Steadicam Deluxe Docking Bracket attaches to most C-Stands for docking and balancing your sled. It is compatible with Aero and Zephyr systems, and it features a sliding and lockable top spar, as well as a 1/2" balance pin, with arm hanger. A tethered locking pin secures your Aero or Zephyr Steadicam to the docking bracket, and the tether helps prevent you from losing the locking pin. Slide the top spar to balance it, then lock the balance plate in place.
