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.
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. Rotating/tilting complete arms mount to a bench or a wall. Secure the object you want to position to the attaching end plate.
Any-which-way complete arms bend and stay in position. They do not have a ball; affix a screw-on base (sold separately) 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.

Mobile Device Positioning Arms
Keep smartphones and irregularly-shaped devices, such as radios, in sight and within reach. These arms mount to a variety of surfaces and have 360° range of motion thanks to their ball-and-socket joints. Tilt or rotate them for a better viewing angle and lock the joints in place.
Arms for smartphones have spring-loaded brackets to grip the outside of your smartphone while leaving the screen visible.
Arms for irregularly-shaped devices hold mobile devices that don’t have a uniform shape, such as radios and GPS navigators. They have rubber fingers that adjust to fit around curves, avoid antennas, and grip asymmetrical devices.
Clamp-on rectangular bar-mount arms have a base that fits around rectangular parts, such as square posts, t-slotted framing, and rails.
Clamp-on pipe-mount arms attach to round bars, pipes, and railings using adjustable jaws. They’re commonly used to mount screens to cart handles.
Magnetic-mount arms cling to magnetic surfaces. They have a strong enough hold to be mounted from any orientation, such as on the side of a machine or overhead on a ceiling.
Suction-mount arms are ideal for mounting devices onto flat surfaces and windows, such as the windshield of your vehicle. The suction cup base is strong enough to keep the arm securely mounted in any orientation.

Tablet Positioning Arms
Position your tablet within view while keeping your hands free to work. These arms mount to a variety of surfaces while keeping a secure grip on your tablet.
Bar-, pipe-, magnetic-, suction-, and threaded-stud-mount arms have ball-and-socket joints that give them a 360° range of motion. Tilt or rotate them for a better viewing angle and lock the joints in place.
Clamp-on rectangular bar-mount arms have a base that fits around rectangular parts, such as square posts, t-slotted framing, and shelving units.
Clamp-on pipe-mount arms attach to round bars, pipes, and railings using adjustable jaws. They’re commonly used to mount screens to cart handles.
Magnetic-mount arms cling to magnetic surfaces and have a strong enough hold to be mounted from any orientation, such as on the side of a machine. They’re good for creating a temporary display because they’re easy to move from place to place.
Suction-mount arms are ideal for mounting tablets onto flat surfaces and windows, such as the windshield of your vehicle. The suction cup base creates a strong hold to keep the arm mounted from any orientation. They’re easy to remove and install, so they’re good for when you want a temporary display.
