Why this fits you

Right size. Built for 4.5 – 5.5 m hulls — 1600 × 1100 mm frame, not a universal-fit compromise.
Quick, drill-free install. Bolts on with heavy-duty galvanised U-bolts. No welding, no drilling — doesn’t touch your trailer’s structure.
Marine-grade stainless frame. Patented adjustable bracket — fits different hull widths without any change to the trailer.
Heavy-duty mesh. PVC double-weave, YKK zipper panels, 2000 N tensile strength. Stones get absorbed and redirected to the ground — not into your gel coat.
ADR compliant. Meets ADR 13/00, VSB 1 and ADR 42. Tested to ISO 16750-3 (vibration) and ASTM B117 (salt spray) / D3170 (stone chip).
In stock, Victoria warehouse. Dispatched within 24 hours. Free shipping Australia-wide.
