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.

Tablet and laptop holders have spring-loaded brackets that adjust to fit most tablets and compact laptops. They have a universal AMPS mounting hole pattern. They do not have a ball; affix a screw-on base (sold separately) to attach to a connector.
6" holders have a VESA (Video Electronics Standards Association) standard mounting hole pattern in addition to an AMPS mounting hole pattern.
Laptop Positioning Arms

Set up your laptop where you normally couldn't, such as on a cart handle or vehicle. These arms attach to surfaces to create a secure mounting point for your laptop. Their base is adjustable to fit a variety of laptop sizes.
Clamp-on pipe mount arms attach to round bars, pipes, and railings with two adjustable U-bolts. They have two ball-and-socket joints—one below the laptop holder and one above the base. Each joint rotates 360°, so you can move these arms in any direction and lock them in place.
Screw-on arms fasten to flat surfaces, such as the floor of your vehicle. These arms have three pivot points that rotate 360° and lock in position. A ball-and-socket joint connects the arm and the laptop holder, so you can tilt your laptop for a better viewing angle.
