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.

Bend-and-Stay Positioning Arms
Stronger and with greater load capacities than gooseneck-style positioning arms, these arms keep their shape even when moving or when exposed to vibration. They’re often used in robotics and conveyor applications when frequent repositioning isn’t required.
All accessories include the necessary hardware for attaching them to arms.
Ball-and-socket adapters and ball-and-socket connectors allow 360° rotation and up to 90° tilt. A locking knob keeps them in place.

T-Slotted Framing Positioning Arms
Make your T-slotted framing workstation more ergonomic. These positioning arms let you move tools and other items within reach, reducing fatigue and streamlining repetitive processes.
Extended positioning arms lock into position when you tighten the screws in the joints. Those with a cable-routing hole are hollow, so you can route cables through them.
Ball-grip positioning arms have ball-and-socket connections, so the entire arm moves 360°. Secure items using the mounting plate.
Arms with AMPS mounting hole pattern are often used on GPS units, cameras, and other small electronics.
