How do I use the Black Jack Towball Weight Gauge to check my caravan's down ball weight?

Place the gauge under your trailer coupling with the trailer level and using the jockey wheel gently lower the trailer tongue onto the gauge until it shows the weight. This gives you an accurate down ball weight reading, helping you set up your caravan safely.

What is the maximum weight this towball weight gauge can measure?

This gauge can measure down ball weights up to 400 kg, which covers most caravans and trailers for safe towing.

Why is it important to have the correct down ball weight on my towbar?

Having roughly 10% of your caravan's total weight on the towbar helps prevent trailer sway, improves vehicle control, and ensures safer towing. The gauge helps you get this balance right.

Is the Black Jack Towball Weight Gauge durable and easy to carry?

Absolutely. Made from strong steel this black gauge is compact, sturdy, and built to last, making it easy to store and use wherever you go.

Can this product really remove all guesswork when setting up my caravan?

Yes! Many customers find the gauge straightforward and reliable, giving a clear reading of down ball weight so you can confidently adjust your setup and tow safely without second-guessing.
