The Chief KRA221B is an expansion arm kit for Kontour K1C column-mounted monitor arms. It lets you add another arm to a K1C installation that is already in place, the most common use being turning a single-arm K1C120 into a dual-arm K1C220. Additional kits can be used to build out a third or fourth arm for shared center-of-table workstations; four-arm configurations require the KRA226 center-of-table grommet plate. Each arm supports monitors from 5 to 22 lb. Expanding an existing column is quicker and less wasteful than replacing the whole mount when a user needs another screen, and the black finish keeps the added arm consistent with the original installation.
