Our 55” telescoping double cam lock support poles have been tested to hold up to 170 lbs. That’s over twice the weight of standard thumbscrew mooring poles. With two die-cast camlock collars, they offer superior adjustability. The aluminum tubing is anodized, heat-treated, and has a ribbed profile for increased strength and lightweight. We use fully synthetic TPR rubber Grey bottom crutch tips that will not scuff or mar your boat flooring. This pole comes with a swedge and snap tip for easy use with different boat covers.
