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.

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.

Hand-held device grips adjust for a secure hold.
Styles G and H do not have a ball; affix a screw-on base (sold separately) to attach to a connector. Maximum load capacity is based on the screw-on base you choose.
Style G have a spring-loaded top bracket that expands, so you can insert your tablet. For a secure hold, the bracket clamps down on your device. They have a keyed lock to prevent your tablet from being removed once it’s in the holder.
Style H hold 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 irregular shapes.
Rotation adapters allow your device to be rotated between landscape and portrait mode without unlocking and adjusting the entire positioning arm.
These adapters can only be used with hand-held device grips that do not include a ball and have an AMPS mounting hole pattern. Affix a screw-on base (sold separately) to attach to a connector.

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.

Monitor and Keyboard Positioning Arms
Bench-Top
Mount Shown Installed
Your entire workstation mounted on a single arm. These arms have two plates, each with its own industry-standard mounting pattern. Connect monitors, tablets, keyboards, and other compatible devices to them. Swing your keyboard out of the way or tilt your monitor for a better view—these arms have ball-and-socket joints for 360° range of motion. To keep a configuration, simply lock the joints in place.
VESA (Video Electronics Standards Association) mounting hole patterns attach to monitors. AMPS mounting hole patterns attach to keyboards. To connect two devices with VESA mounting hole patterns, use adapters (sold separately) to convert the AMPS end mount to a VESA end mount.
Rectangular bar-mount arms have a base that clamps around rectangular parts, such as square posts, t-slotted framing, and rails. They’re commonly used on forklift cages.
Bench-top mount arms have a mounting plate at their base that screws into a surface, such as a tabletop or vehicle floor.

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.
