The Round Pad Eye is used by many manufacturers to run rudder lines or deck lines along the side of a boat. They are made of high quality nylon to ensure they can take the abuse and strain that today's kayakers can dish out. Sold individually.
Worked very well for kayak rudder lift lines
I love using these...especially for rudder lines. They really keep deck lines smooth and give installs a much more professional look. Very easy to install, even with well nuts as long as you use longer screws.
