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.

Pivotal parts for building solar supports

April 26, 2023

Ordering process and shipping was facile and very quick. Upon arrival, I found the items to be a higher level of quality over fittings available from other suppliers. The parts allowed me to design a nice tilting panel holder. Thanks!

We’d love to see pictures of that tiling panel holder – you’d be surprised how many people are trying to do just that.
