Ball-Grip Positioning Arms
Ball-and-socket connections allow 360° positioning. Choose a complete arm or select a base, connectors, and a plate, grip, holder, or tray to build a complete arm.
For technical drawings and 3-D models, click on a part number.
Rotating and rotating/tilting complete arms have handles to lock joints into position. For the rotating/tilting complete arm, mount the base to a bench or wall and secure the object you want to position to the attaching end.
Any-which-way complete arm bends and stays in position. It does not have a ball; a screw-on base (sold separately) must be secured to the attaching end to attach to a connector.
