How to install Chief MAC119B Swing Arm Adapter

To install the MAC119B Swing Arm Adapter, begin by confirming that your mounting surface is suitable for supporting a 100 lb load and that you have access to the Chief arm system with compatible mounting points. Unpack the MAC119B kit and lay out all hardware, verifying that you have the correct screws, spacers, and washers for your display and wall or cart setup. Attach the adapter to the display using the included mounting hardware that matches your display’s VESA or mounting pattern, ensuring all screws are tightened securely without over-torquing. Next, align the adapter with your swing arm or wall/cabinet mount, slide or lock it into position as required, and tighten the connection to eliminate unwanted movement. Once attached, carefully connect any required cables and route them through the dedicated channels or clips to maintain a clean, unobstructed layout. With the display secured, perform a full range of motion tests—extend, retract, tilt, rotate, and lock—to confirm smooth operation and stable positioning. Finally, recheck all fasteners after a short period of operation, and adjust locking mechanisms as needed to maintain precision and safety in everyday use.
