New and improved star logo

We’ve re-engineered the link in our stainless steel articulated hinges for a tighter, smoother action.

Available now.

Buy them individually or as part of our assembled folding struts.

Gemini Marine Product’s patented articulated barrel hinge and GemLock folding strut assembly bring simplicity and elegance to your boat. When opened, a perfectly placed pair of push buttons lock a sleeve in place over the hinge so the strut only folds when you want it to fold. The design ensures that any strut can also double up as an ocean-rugged grab rail even when also acting in another capacity.

Use them to:

  • Make spreader bars on bimini tops that eliminate tensioning straps and give your boat 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.

Assembled GemLock folding struts

Ready-to-install assembled struts are available in 7/8” and 1” tubing using 316 marine grade stainless steel throughout. Both sizes come in 3′ or 6′ lengths – simply cut to your required length and install on your boat.

GemLock folding struts

GemLock 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, making the entire length of a strut a great grab rail.
