This Proaim Rotating Turnstile Mount features a Mitchell mounting base for use on the Proaim dolly or other compatible dollies. It attaches to the dolly and provides an Elemac/Euro mounting system for cine accessories such as a bazooka or offset arm. In addition, the turnstile mount also provides two accessory seat studs that rotate around the mount. This allows you to add accessories such as riser seats or light stands that move along with your dolly. You can lock the rotation to set the position of the studs using the integrated locking lever.
The turnstile mount fits onto your Mitchell mounting plat and locks into the keyway so it won't rotate
It has four through-holes and requires four bolts to safely secure it to the mounting surface
