Mod Spacer™ Cam


The Mod Spacer Cam sets the inter-row spacing between solar panels.. With it’s twist-release feature, it will never get stuck between panels.


SKU: MS-C Category:


Tired of fumbling with mid clamps and other home-made spacers you’ve stuck between two solar panels? You’ve come to the right place!

The Mod Spacer helps solar installers set the gap between solar panels. The patent-pending cam mechanism allows the spacer to collapse when you’re ready to remove it, relieving pressure and friction from adjacent panels. This makes every install go faster, but it’s particularly handy on steep roofs, where the weight of the panels makes it extremely difficult to remove traditional spacers. To use, simply:

  1. Slide the spacer between two panels in the “install” position
  2. Fasten panels to racking
  3. Twist the spacer to the “remove” position
  4. Pull the spacer out

Damn, that was easy!

Other features of this version include:

  • Big handle is easier to grab than traditional spacers
  • Plastic construction won’t scratch panels or pose a drop hazard
  • High-vis color so you won’t leave it on the roof by accident (been there done that)

Which Spacer do I need?

Installers have strong personal preferences, so we developed both the Cam and the Peg to make everyone happy!

We recommend the Mod Spacer Cam if you tend to work on small, complex or steep residential roofs. It’s small and versatile, and particularly helpful on steep roofs. The Cam’s twist-release feature prevents it from getting stuck between two panels – no matter how heavy the panels or steep the roof. The Cam has earned the nickname “fidget spacer” from our field testers who can’t stop clicking it between open and closed positions (we can’t decide if that’s a benefit or a drawback). One downside of the Cam is it cannot be “perched” on the upper edge of a solar panel like the Peg.

We recommend the Mod Spacer Peg if you tend to work on large, relatively flat arrays. It is suitable for residential, commercial and utility-scale jobs. The Peg cannot collapse for easy removal like the Cam, but unlike the Cam (or a mid clamp), it can be perched on the upper edge of a single solar panel. Some installers find this speeds up their workflow. Large arrays can be installed faster using the Peg in its “bar mode,” where several spacers are mounted to a stick of EMT.

The Mod Spacer is still in development, but it’s a hit with our field testers. We’re constantly improving the product, so what you receive might look a little different from the photos above. We’d love to hear what you think of the Spacer – please leave a review on this page or contact us with your comments!
