Our telescoping cam lock support poles have been tested to hold up to 120 lbs. That’s over twice the weight of standard thumbscrew mooring poles. They have a polycarbonate collar and stainless steel components. The aluminum tubing is anodized, heat-treated, and lightweight. We use fully synthetic TPR rubber Grey bottom crutch tips that will not scuff or mar your boats flooring. This pole extends to 56" and collapses to 30.5".
