Stops fine dust and insects getting through your 150 x 100mm pressed aluminium vent — without killing airflow. The rear stays open, so driving forward draws air out of the van instead of forcing bulldust in. It also takes the bite out of drafts — with the opening facing back, wind doesn't blast straight through the vent while you're driving or parked up in a blow.
Made from UV-stable material built to live outside — harsh sun, long hauls, red-dirt corrugations. Matte finish. Made in Australia.
