Product descriptions below.

Choose from our selection of quality hardware


Eye ends – Used to cover the end of cut tubing to attach other components, like post or fork mounts or quick release pins. Available in three sizes. REMEMBER: If you are using our 1 1/4″ mounts to connect to smaller tubing (using either 7/8″ or 1″ eye ends), you will need to drill out the hole in the top of the smaller eye ends to fit the heavy duty bolts in the top of the larger mounts. Please phone us with questions.

Slip tees – Used to join pieces of tubing with a clean, strong junction. Available in two sizes. We also have a tee that opens like a book on a hinge – only available in 7/8″.

Deck hinges – Used to secure tubing frames to flat surfaces. Your choice of universal, 90degree, angled, swivel with an integrated eye end, two types of Accon mounts and the angled shim that can be used with them.

Stainless steel sleeves – Used to secure a GemLock folding strut in a locked, open position, but also useful for other jobs. Available in 4 sizes.

Jaw mounts – If our offset mounts aren’t quite what you are looking for, these sliding and split jaw mounts might be just the thing.

Spring balls – Used to hold a stainless steel sleeve in its locked position on a GemLock folding strut and then release it when you want to fold the hinge.

Snap tool – Don’t struggle with your canvas snaps, use this professional snap tool to attach and remove snapped canvas with ease.

Post screws, clamp bolts, washers and set screws – Lost a little something overboard? Have no fear, we’ve got what you need right here to replace lost components of Gemini Marine Products. Sold in sets of six.

Drop nose quick release pins – Perfect to use with our fork mounts or jaw mounts when you want the speed or ease of disconnecting frames without tools.

Great Quality

I have not used at this time for the original intended purpose. I will keep the clamps for future use.

Stainless steel hinge

December 24, 2019

These were not round.

Had to take them to machine shop and have them turned to fit. The shank on them is not .065. Closer to .875. Being they were larger and out of round. They had to be turned.

Luckily I work for a large airline and was able to take them to work.

Response from Gemini Marine Products

Thank you for this feedback. To help clarify: The description for this item clearly states, “Size: 1″ stainless steel hinge for use with .065″ wall thickness stainless steel tubing” – the insert portion of the hinge is not .065″. That is the wall thickness of the stainless tubing for which is it designed to be used. While it is possible it was out of round, the hinge is purposely designed to be slightly small for 1″ x .065 tubing, and the 0-ring is intended to compensate for any distortions in either the hinge casting or the tubing. We’re sorry this confusion caused you extra work, but we’re very happy you like them.
