ALZO Liberator Battery Door Plate for Panasonic G7 Solution to allow battery and memory card access when camera is mounted on a tripod or a rig Includes 2 tripod mount thread holes; one of the holes is positioned at the lens focal point and the other is farther from the battery access door to allow for usage with very large camera quick releases, like those on Pro video tripods Special 3M grip rubber base prevents rotation, and the adhesive pad on the bottom of the plate provides a strong bond, but it is not permanent; the ALZO Liberator Battery Door Clearance Plate can be removed at any time without leaving any residue on the camera Can be used on any camera with a 1/4 inch x 20 tripod mount threaded hole; accepts all tripod quick release plates Can support cameras and gear up to 5 pounds; 5 year warranty
