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.

(Concave fork mount)
I’ve just received my rail mount and it seems to have excellent quality. I’m very happy with the purchase, customer service and speed for international shipment.

We’re so happy to hear from you! Thank you for your interest in our products and happy sailing.
Concave post rails
Purchased 4 concave post rails to use in mounting 4 x 175 watt flexible solar panels to the Bimini frame on my 40.5 Hunter Legend. Panels will be supported by a frame of 7/8″ 316 stainless tubing joined by 90 deg corner fittings and T Fittings along the two interior rails all in 316 stainless. Used your drill guide Pro to mount the posts to the Bimini and the solar frame rails to the posts. Had to use a slightly longer bolt than one supplied with the posts to reach through the 7/8″ stainless tubing but all is secured and the panels are making power for both the 2 x 8D AGM house batteries and the AGM start battery. Thanks for the prompt service on my order delivery.
Response from Gemini Marine Products
You are most welcome. We’re so glad to make things a little easier for you.
Drill Steady Pro
Great piece of kit, worked as described. Great for initial hole drilling and also as a pilot hole for a larger bit if a bigger hole is required.
Response from Gemini Marine Products
Yeah it’s a handy little thing, isn’t it? We’re glad you like it.
