ACT Monitor arm 49" office premium gas spring pole mounted 2 monitors

The ACT AC8343 Office Premium monitor arm creates an ergonomic, space-saving workspace for up to two monitors. Constructed from full metal, the dual monitor arm supports two displays up to 49" and 20 kg each with VESA 75x75 and 100x100. Curved screens and stacked configurations are supported. Height is adjustable up to 70 cm (measured from the desktop to the centre of the VESA plate). Both clamp and grommet mounting hardware are included; the top-mount clamp provides a clean, space-saving appearance.

Advantages

The solid metal construction offers durable support for two heavy screens while the gas spring enables smooth, tool-free height adjustment. Three pivot points plus tilt, swivel and rotate functions allow flexible ergonomic positioning to reduce neck and shoulder strain. Integrated cable management keeps cables tidy, and adjustable gas spring tension adapts to different monitor weights. Detachable VESA plates and included anti-theft screws simplify installation and security.

How to use

Attach the pole-mounted monitor arm to your desk using either the top-mount clamp or the grommet fixings supplied. Secure the detachable VESA plates to each monitor (VESA 75x75 or 100x100) and hang the monitors on the arms. Use the gas spring to set the preferred height and adjust tension if needed to match monitor weight. Tilt, swivel and rotate each screen to achieve the desired viewing angle. Route cables through the integrated cable management channels to keep the workspace tidy.

Usage recommendations

For safe and optimal operation, confirm each monitor’s weight does not exceed 20 kg and ensure desk thickness is within the 45 mm maximum. Adjust gas spring tension gradually to match monitor weight and check all mounting screws periodically for security.
