💡 How does a backing plate improve u-bolt strength on square tubing? A backing plate spreads pressure evenly so the bolt stays put without digging into the frame. - It turns the whole setup into a clamp that resists loosening from vibration. - The plate also protects soft wood or thin metal from getting crushed over time. - Builders notice fewer wobbles on trailers and gates once the plate is added. - Overall it gives a cleaner professional finish while keeping the connection sturdy.
