Using the Fender 351 Guitar Wall Hanger is easy. First, choose a suitable wall location. Make sure the wall can support the weight of your guitar. Then, use the included mounting hardware to attach the hanger to the wall. Hang your guitar on the hanger, and the padded yoke will pivot to keep it straight. When it comes to maintenance, keep the hanger clean by wiping it with a dry cloth. Avoid using harsh chemicals as they may damage the finish. Also, check the mounting regularly to ensure it's still secure. If you notice any signs of wear on the hardware or the hanger itself, it might be time to replace them.
