Couldn’t see from the photos if there is. 2) What is the diameter of the center hole? The application in mind is to control two lines on a kite (87″ wingspan). Thanks!

We can also sell these winch parts without the cord at lower cost. Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
