The 8Sinn Nikon Z6/Z7 Cage is a formfitting, 4-sided cage with the right side ergonomically designed with gentle edges to provide a comfortable grip. 1/4"-20 mounting threads all around and a shoe mount on the side allow you to securely attach accessories. There's also a slot on the side for an optional wrist strap. The cage does not interfere with any of the camera's buttons, ports, or slots. It is made from a single piece of aluminum and provides protection all around. Your camera secures to a 1/4"-20 tie-down screw that screws in from the bottom of the cage using an included Allen key.
