Heavy Duty Ball-Grip Positioning Arms

With strength for higher load capacities than other ball-grip positioning arms, these arms have a heavy duty construction. Ball-and-socket connections allow 360° positioning. The base, connectors, and links are hollow for routing wires, cables, and small hoses. Select a base, connectors, link, and plate or mount to build a complete arm.

Ball-Grip Positioning Arms

Ball-and-socket connections allow 360° positioning. Choose a complete arm or select a base, connectors, and accessories to build your own.
To ensure compatibility, select components that have the same ball diameter. Use reducing connectors (sold separately) to pair components with a 1 1/2" ball diameter to those with a 1" ball diameter.

Heavy Duty Positioning Arms

Pole Base, Pole, Pole-to-Pin Adapter, Two
Rigid Connectors, and Pivoting Mounting Plate

Heavy duty construction adds strength for higher load capacities than other positioning arms. Choose a complete arm or select a base, connectors, and plate, bracket, or tray to build a complete arm. The load capacity of an assembled arm is determined by the component with the lowest capacity.

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.
Secure items to attaching-end mounting pads with glue, hook and loop, screws, or other fasteners.
Suspension Arms for Enclosures
![]() All Components Sold Separately | ![]() Example Configuration |
![]() Example Configuration |
Hang your human-machine interface and swivel it around to save floor space and comfortably access touch screens, buttons, and other operating equipment. These suspension arms have already-drilled mounting holes that match our HMI enclosures. Route wire from your HMI components to a machine through a hole that runs through the entire arm. To prevent them from swinging too far and hitting people and equipment, locking pins let you restrict how far these arms rotate. Brakes lock their position into place.
Customize a system for your application—you can create hundreds of different variations. A complete suspension arm requires at least a base, a tube, and a mount. Add components to extend your arm up to 80” from the base and expand its range of motion. Arms without a connector support up to 180 lbs. Those with a connector support up to 135 lbs., but the load it can hold decreases by 2 lbs. for every 1” over 40” from the base.
Mounts connect your arm to an enclosure.
