How to install Chief Thinstall 18" Extension Monitor Arm Wall Mount

• Prepare the tools and space: Before you begin, gather a drill, spirit level, stud finder, and appropriate wall anchors or screws for your wall type. Confirm that you have access to wall studs if mounting on drywall for maximum support.
• Attach the wall plate to the structure: Mark the locations for the wall plate and drill pilot holes. Secure the wall plate to the wall using sturdy screws or anchors that align with the stud locations. Use a level to ensure the plate sits perfectly flat.
• Install the extension arm to the wall plate: With the wall plate secured, connect the arm to the plate according to the manufacturer’s instructions. Tighten fasteners to the recommended torque to prevent unwanted movement while maintaining smooth action.
• Prepare the monitor mounting hardware: Attach the VESA mounting plate to the back of your monitor using the appropriate screws. Ensure screws are tight and that the plate sits flush against the monitor.
• Mount the monitor and configure tension: With the arm extended or retracted as needed, align the VESA plate with the mounting head on the arm and secure it. Connect video and power cables, then test the range of motion. Adjust the Centris tension as necessary to balance ease of movement with screen stability.
• Final checks and cable management: Ensure all connections are secure, route cables through the built-in management channels to maintain a clean appearance, and verify that the monitor remains stable through full extension and retraction cycles.
