Gemini Marine Products sliding side mount support a rigid solar panel

Split and sliding side mounts

Our stand-offs stand out

Our unique stand-off type mounts either slide 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.

No disassembly required with our hinged slide mount.

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.

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.

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.

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.

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