These telescoping cam lock support poles have die cast collars and stainless steel components. 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. These poles come with a snap end already installed. To protect your boats flooring from scuffs or marring, we use a synthetic TPE rubber crutch tip. For added stability, use our swivel pole bases.
