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.

Base is for use with straight and tee connectors.

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.
Clamp-on bases have two arm attachment locations. Place arms straight or at a right angle from the clamping screw. Clamp-on bases with a rubber V-block can be mounted to rounded surfaces such as pipe and railings.

Create-Your-Own Workholders
Build a custom clamping system for holding lightweight objects such as beakers and laboratory equipment. First choose a base, and then add rods, connectors, and clamps.
Suspension Arms for Enclosures
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.
Bases mount your arm to a surface. Wall bases mount to a wall, the side of a machine, or another vertical surface. Bench-top bases mount to horizontal surfaces, such as the top of a machine.
