The Joby Mini Pivot Arm with Thumbscrew is a multi-functional compact pivot arm that attaches your GoPro or 1/4"-20 mount action camera to a 1/4"-20 threaded hole. It features a base which screws into any 1/4"-20 socket, adapting it to a three-prong mount for attaching a GoPro housing or frame. A long GoPro thumbscrew is included. For use with other action cameras, the Mini Pivot Arm comes with a 1/4"-20 adapter which, in addition to the Mini Pivot Arm, can be used with any GoPro accessory to make it compatible with 1/4"-20 mount cameras.
