Brand new, unopened. Set of 2. Purchased from Amazon, but no longer needed as I bought a different monitor arm. ※ The following is the product description. A stylish V-shaped monitor arm with a slimmer design than the LX arm, requiring no assembly. It folds compactly when not in use, allowing for a wider workspace. Desk clamp included. Can be attached to surfaces 12-32mm thick. Grommet mount not included. Separate grommet mount (98-110) is required. The grommet mount can be attached to holes with a diameter of 8-31mm and a thickness of up to 32mm. Made of durable aluminum. Manufacturer's warranty is 10 years. The arm itself arrives assembled, so you can start using it immediately after attaching the monitor and mounting it to your desk. The pan has a stopper that stops at 180°. Ergotron's unique Constant Force technology allows you to adjust the monitor position with a light touch. There is no deterioration over time like with gas spring types.
