Product Overview
The Chief KSA1003B Extension Arm adds 6.5 inches of reach to Chief F-series and K-series monitor arm mounts and pivot/tilt wall mounts. It suits conference rooms, training rooms, and commercial workstations where a monitor needs additional extension. This model ships in a black finish.
Product Description

The KSA1003 Extension Arm Accessory provides 6.5" of additional extension for F- and K-series monitor arm mounts and pivot/tilt wall mounts. Integrators use it to push a monitor farther from the mounting point, improving range of motion at desks and collaboration stations. The accessory is available in silver or black, with this model finished in black to match surrounding hardware. To preserve mount stability, do not exceed more than three arms in a single configuration. Maximum weight capacity is 25 lbs for any combination of arms that includes a height-adjustable arm, and 30 lbs for three static arms. Plan the configuration around those limits to keep the mount within its rated load. Need a lighter finish? See the silver KSA1003S, or browse Chief arms and accessories in the Chief collection.
