Use the Kontour™ KRA221SXRH K1C Reduced Height Expansion Arm Kit to add an additional K1C reduced height monitor arm to an existing K1C installation. This provides a fast and easy means of upgrading from an existing single-arm K1C120SXRH to a dual-arm K1C220SXRH configuration. The KRA221SXRH can be used to add a 3rd and/or 4th arm to a center-of-table multi-workstation configuration, using the KRA226 grommet plate accessory.
