The Chief MAC1003B is an arm extension kit for the Chief J-Series family of swing arm display mounts. It is an add-on accessory, not a complete mount: it is installed on an existing J-Series arm to add an extension section when the standard arm configuration does not reach far enough for the layout of the room or workstation. The kit is finished in black so it blends with matching black J-Series hardware, and it is offered in both black (MAC1003B) and silver (MAC1003S) versions. Because extending an arm changes the leverage on the wall and the arm joints, confirm the exact J-Series model you are extending and its rated capacity with the extension installed before ordering. Chief's published data for this kit is limited, so please contact 4TEC Direct if you need help confirming fit for a specific J-Series arm.
