Vico Plastics is a manufacturer of plastic and aluminum marine accessories. We supply boat cover support & venting systems to boat manufactures, marine distributors, and canvas upholstery shops. Our Patented Boat Vent II and Cam-Lock Support poles provide ventilation and tenting for mooring covers, travel covers, and storage covers. The purpose of the vent and pole is to exhaust moist air and heat without letting any rain or moisture in. This aids in preventing mildew, fungus, and harmful bacteria from growing rampant in unvented boat interiors. Installation time can be reduced to seconds using our custom circle hole cutter. For proper support, Boatvent II should always be used along with an adjustable mooring pole (tent pole). It is extremely important that a vented well fit cover be tied down tightly, by using tie downs such as our Quickie Ties. Our new cam lock support poles are constructed from the finest and strongest anodized aluminum alloys. Our ribbed design provides the maximum strength to weight ratio. The rest of the components are stainless steel. Our poles can hold up to 170 lbs of down force, more than double the capacity of the old thumbscrew style poles.
