Ergotron 24-317-026 Mounting Arm 19.5-Inch Height Adjustment

Ergonomic Sit-Stand Workstation Arm

The Ergotron 24-317-026 mounting arm converts an existing desk into a height-adjustable sit-stand workstation with 19.5 inches of vertical travel. It supports a monitor and keyboard tray that move together for proper ergonomic alignment. Office workers and home users who alternate between sitting and standing throughout the day will benefit from the flexible positioning.

Clamp Mount Installation Fully Assembled

The unit arrives fully assembled and attaches to the back or side of a worksurface using an integrated clamp, avoiding the need for professional installers or permanent modifications. Its patented CF counter-balance technology enables fluid one-touch height changes without levers, cranks or motors. The only common difficulty is confirming the desktop thickness and edge clearance suit the clamp dimensions before purchase.

Fixed Vertical Range Single Surface Dependency

Height adjustment is limited to the stated 19.5-inch range, which may not suit very tall or very short users without an additional riser. The arm requires a sturdy, fixed mounting surface and cannot be used on glass tops, thin partitions or unstable desks. When folded away, the keyboard tray and arm swing clear but remain attached, so the host desk must accommodate the stored projection.
