Hinges and folding struts

Gemini Marine Product’s patented hinge and strut assembly bring simplicity and elegance to your boat.

Use them to:

  • Make spreader bars on biminis that eliminate tensioning straps for a cleaner look and better cockpit access.
  • Install grab rails and pusher bars on dodgers that fold quickly for easy storage.
  • Make folding tables and T-Tops, openings in life line rails and stowable jumper seats.

Struts lock in position with a sleeve that slides over the hinged joint and is secured in position with a spring ball on either end. Our struts only fold when you want them to fold, and the entire length of a strut acts as a grab bar.
