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 difficult to remove traditional spacers. To use, simply:
- Slide the spacer between two panels in the “install” position
- Fasten panels to racking
- Twist the spacer to the “remove” position
- Pull the spacer out
Dang, that was easy!
Other features of this version include:
- 2 different gap sizes available
- 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)
What size Mod Spacer do I need?
We offer two sizes: 1/2″ and 20mm (3/4″).
- A 1/2″ Mod Spacer will leave a 1/2″ gap between adjacent solar panels.
- The 20mm Spacer measures exactly 20mm, which is just a hair over 3/4″. The table below summarizes which Mod Spacer to use based on your solar racking system.

|Slick Tools recommended

|IronRidge XR Flush Mount
|Quickmount Q Rail
|SnapNrack Ultra Rail
*No minimum gap size specified. However, mid clamps leave a 1″ gap between panels.
**SnapNrack allows as small as 1/8″ gap, but recommends 3/4″ to promote airflow and allow for longer roof attachment spans in some circumstances.
Which version of the Mod Spacer should I buy – Cam or Peg?
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.
As with every Slick Tool, we’re constantly revising and improving this product using feedback from our awesome field testers and customers. What you receive might look a little different from the photos above. We’d love to hear what you think of the product– please leave a review on this page or send us your thoughts!
