Sliding side mount under solar panel

Split and sliding side mounts


Expand your possibilities

Our stand-offs stand out


Our unique stand-offs, both split and slide mounts, either slip over the end of tubing or clamp on by opening the hinged jaw. Originally designed for mounting solar panels, these mounts dramatically increase the possibilities for updating and adding all kinds of attachments to dodgers, biminis, davits and rails.

Slide mounts with an extensive range of uses


Crafted from 316 marine grade stainless steel, our hinged and sliding offset mounts are available for use with 7/8”, 1” and 1¼” tubing. With them you can:

  • Adding tensioning and support struts
  • Adding spreader bars
  • Attaching solar panels on your bimini top – this hardware is great for DIY solar additions
  • Attaching antennae, awnings and foldaways for cutting boards and electronics pads
  • Adding grab rails on dodgers, stanchions
  • Fixing binnacle or aft rail lines

It’s almost easier to say what you can’t do with our mounts…

*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.

Hinged slide mount


No disassembly required

Unlike sliding side mounts, which must slip over the end of a tube, split jaw mounts can attach anywhere, including on frame bends, without disconnecting frame structures. This makes additions, installations, removal for storage and upgrades a breeze – even midseason.

Sliding side mounts


A little sleeker

Our sliding side mounts are less obtrusive than our split mounts (and a little easier on the pocketbook). Great for new builds or removable installations.

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.

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.
