## Description

## Features

- This component belongs to the Tackform Enterprise Series which is based on a large 1" rubberized ball. The entire series consists of various bases such as suction cups, cup holder mounts, headrest clamps, table clamps as well as phone, tablet and action camera holders.
- Made of composite ABS plastic which provides solid strength while remaining light.
- Use this to replace a shorter or longer arm to get the perfect device position. You could also use one of the ball to ball adapters to provide additional length as well as additional points of articulation.
- When compared to a two knob arm, this has limited movement options which makes it a great choice for mounts that won't be adjusted often.
- The Tackform Enterprise Series is a collection of components focused around a large 1" rubberized ball. Our Enterprise Series includes completely finished mounting solutions as well as individual components for your DIY crowd. We're ready to mount to your car, truck, bike, motorcycle, airplane, office, kitchen or anywhere else!
