Boat owners, this Vico Marine support system makes covering your boat SO much easier! The telescoping pole extends from 39 to 70 inches with a cam lock mechanism that holds securely without those annoying thumb screws that always strip out. Tested to support up to 120 pounds - that's more than twice what standard poles handle, so no more collapsed covers from rain or snow accumulation. The anodized aluminum tubing has a ribbed profile for extra strength without adding weight. The Boat Vent 3 is a major upgrade from previous models with easier installation, better venting efficiency, improved grip, and adjustability - it installs in less than 15 seconds! The swivel pole base is genius - it rotates to find the perfect angle and has a thermoplastic rubber bottom that grips your boat floor without scratching or marring the surface. The synthetic TPR rubber crutch tips won't scuff your flooring like hard plastic would. This complete combo includes one 70-inch pole, one pole base, and one Boat Vent 3 - everything you need for proper boat cover support. Vico Marine is US-based in Wisconsin, so you're supporting American manufacturing. Seriously, if you're tired of struggling with flimsy support poles or dealing with water pooling on your cover, this system will save you time and protect your investment.
