Our telescoping cam lock support poles have been tested to hold up to 170 lbs. That's over twice the weight of standard thumbscrew mooring poles. These light weight carbon fiber poles have a die-cast collar and stainless steel components. We use fully synthetic TPR rubber Grey bottom crutch tips that will not scuff or mar your boats flooring.  This specific pole is 38" when collapsed and extends to 96" maximum. This pole works with Vico Marine's Boat Vent 2.
