Whitecap Push Up Ski Tow Pylon - Vertical Mount 
Description: 316 S.S. ski pylon - easy to install! All that is needed is a 1-5/8" hole saw and a wrench. Comes with a washer and nut already installed. When open, the pylon head has an opening to hold the tow rope and also rotates 360 degrees to give the skier the same effect as a standard pylon.
