Are you looking to make your towing experience safe and controlled? If so the Trojan Tow Ball Trailer Weight Scale is for you! All tow vehicles have a maximum tow ball down-weight rating, and exceeding this weight or even being too light - can lead to trailer sway, loss of traction, poor steering control, or sagged suspension in your vehicle. The Trojan Trailer Scale helps you fix this, by giving you a reading of your trailer weight at the coupling; so that you can shift your load forwards or backwards - to achieve the perfect weight. The scale features a sturdy steel construction, with a soft head to protect your ball coupling. The laser etched gauge won't wear off, and is easy to read and the high quality compression spring will provide readings up to 350 kilos -even after 1000 uses. How easy is it to use? To use, simply position the trailer in a safe spot and attach it to the soft ball head of the trailer weight scale as you would to the tow ball of your car. The scales will then provide a weight rating. Easy!
