ASSEMBLY AND INSTALLATION

The KRA221 add-on arm can be used to create two-display, three-display or four-display configurations. The installation steps vary slightly for each configuration. In order to create a four-display configuration, the KRA226 grommet accessory must be used as well.

Two Display Configuration

IMPORTANT ! : The only acceptable two display configuration is for the arms to be installed on opposite sides of the column! See Figure 4 for acceptable and non-acceptable configurations.

1. Remove cap from K1C column. (See Figure 1)
2. Loosen screws holding arm to column and slide arm off of column. (See Figure 1)
