How do I measure my trailer?

Measure the total length, width, and height of your trailer cage in centimetres — make sure to include any hinges, latches, and other protruding hardware in your measurements. Length is measured from the front to the back, width from side to side, and height from the base of the cage to the top rail. Always double-check before ordering to ensure the best fit.

What payment methods do you accept?

We accept Visa, Mastercard, American Express, Google Pay, Apple Pay, and Afterpay. All payments are processed securely through our encrypted checkout.

Do I need support bars with my trailer cover?

Support bars stop water, leaves, and debris from pooling on top of your cover. Without them, standing water sits and adds unnecessary weight, which can cause sagging over time. The bars create a raised shape so everything runs off naturally — keeping your trailer cleaner and your cover sitting the way it should.
