It extends up to 23.5 inches (59.7 cm) and features VESA compatibility for 75 x 75 mm and 100 x 100 mm mounting patterns, making it ideal for optimizing your workspace with a secure and ergonomic display setup via its desk clamp, which accommodates surfaces up to 2.7 inches (68 mm) thick.

Monitor mounts have zero ongoing costs. Once installed and tensioned correctly, they operate for years with no maintenance.
