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.

Best Mounts Period!

March 28, 2022

These are the best way we have found to mount solar panels and other accessories. These mounts work GREAT for mounting solar panels and accessories on any type of boat! They save us time and money for our customers and look great doing it!

Overall Good

Excellent product, a little pricey but they have it. Only downside was the import duty and taxes are not done at checkout so be prepared to pay for this.

Response from Gemini Marine Products

We’re so glad you are happy with your mounts – we love photos if you care to show us how you used them. All the best and happy sailing.

How big a drill bit can I use?

can I use a 1/4″ dia bit?

Response from Gemini Marine Products

Thank you so much for the review. To answer your question, the DrillSteady is designed to take a 9/64 drill bit. If you need something larger, we recommend you use this as your guide hole. All the best and good luck!

Side rail mount

This worked perfect for attaching to our rail. We attached a stainless steel flag pole to it.

Great product.
