Our telescoping cam lock support poles have die cast collars and stainless steel components, allowing them to hold a staggering 170 lbs; that is over twice the weight of standard thumbscrew mooring poles. The aluminum tubing is light weight, anodized, and heat treated to make sure it can withstand any climate, and with the added strength of a ribbed profile this pole is designed to last. Our poles come in a variety of sizes and tip options, including snap, swedge, and plug. To protect your boats flooring from scuffs or marring, we use a synthetic TPE rubber crutch tip. This pole works perfect with the Boat Vent II.
