Hinges and folding struts
Yes you CAN fold stainless tubing
Better access.
Better stowage.
Just better.
Gemini Marine Product’s patented articulated 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. Our step-by-step instructions make it easy – see below.
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.
Don’t forget:
Now you can buy kits to add grab rails or convert to a strapless bimini with ease.
Kits contain all the parts you need to install today.

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 struts lock in position with a sleeve that slides over the joint made with our articulated hinge 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.
Why do you need our folding struts? So you can do things you can’t do any other way.
Articulated hinges
Individual articulated barrel hinges are available in a variety of sizes to meet different needs. Please consult our product specifications for details or call us for advice on which hinge is best for your job.

as always, your products are top shelf – again I removed the set screw and drilled it out for a bolt
Response from Gemini Marine Products
Always happy to make folks happy. We’re so glad they are working well for you.

used the fittings to install a storage box between my dinghy davits – all the fittings worked perfectly – I did drill out the set screws and installed bolts to prevent failure
Response from Gemini Marine Products
Hello there Mr A, So glad to hear these worked out for you. Thanks also for the tip on a new use for our hinges – we’re always super happy to share all the ways our hardware can help on board. All the best for now and happy sailing.
Very happy with purchase
the mounts look great on the arch of our sailboat, holding my solar panels! Easy to set in place. Will buy again when time comes for more panels.

Thank you so much for the feedback – we’re so glad they worked for you, and we look forward to serving you again.
High quality and shipped very quickly.
I’d prefer a product that doesn’t exist yet: curved, fixed length grab rails with swiveled, hinged clamps that don’t require committing to drilled holes in my dodger frame, like studded grab rails do. Gemini should make this!
But these side rail mounts seem like they will work well instead, and price and shipping were better than Sailrite. The stainless casting and finish is perfect quality. I was worried they would not slide over curved tubing, but there is just enough clearance to do so with no problem.

We’re so pleased they did the job for you. Great idea for grabs, too.
Great Service from Gemini
Great service from Gemini from my on-line order placed from Australia. Parts were shipped quickly and lots of feedback from them as to what was happening. DHL air freight let them down with their service though as the 4 -5 days transit turned into 2 weeks as the parts went on a worldwide tour (no reflection on Gemini, they were as frustrated as I was). Very happy with the mounts and will have them and my new solar panels on the yacht in the next week or so.
Response from Gemini Marine Products
Aw thanks Mr W for the kind words and being understanding about the shipping problems we faced. You bet we were frustrated for you! We’re so happy the mounts will work for you. Happy sailing.
Nice product
It is a good product and fit correctly on the rail. However check the screw threads one did not seat completely but that was a small problem.
Response from Gemini Marine Products
Thanks for the kind words and the feedback – we will do as you suggest.
