The Zacuto VCT Pro Tripod Dock allows you to quickly take your camera off the VCT Pro Baseplate and slide it onto the VCT Pro Dock situated on a tripod, dolly, steadicam, etc. The red top plate (sold separately) slides off the baseplate with the push of a lever and into the Dock quickly and easily. With the twist of the mini ratcheting lever, you can securely mount your camera on the Dock. The Dock attaches to your tripod or device via 1/4"-20 and 3/8"-16 mounting screw holes centered in the bottom of the plate.
