Sparehand PS-41L rack is made from all steel and has been black powder coated for aesthetics and corrosion resistance. With its steel construction and 27″ long arms, the Surfboard Rack for Home is designed to hold just about any surfboard ever made.One unique feature about the arms is that they can be mounted upside down or right side up. When mounting the arms right side up, the arm will be angled up 15 degrees relative to the horizon. When mounting upside down, the arms will be angled up at about 5 degrees (almost horizontal). The arms are equally strong mounted in either position, so picking how you want it is simply a matter of preference.
