Trico Wiper Blade Set to suit a wide range of Australian-delivered passenger cars, SUVs and light commercials, supplied ready to fit with no modification required. The adaptor is pre-fitted, so the blades click straight onto the standard arm. Blade lengths are 450mm and 450mm, matching the factory sweep pattern. An aerofoil profile keeps the blade planted at highway speed and prevents lift. Replace blades every twelve months; Australian UV degrades the rubber faster than wear from use. The Natural Rubber wiping edge is precision cut and treated for a smear-free wipe in heavy rain. Every unit is supplied new with a 24 Months warranty against manufacturing defect.
