Description
CritterBlok V2 is here! See the new product page. We recommend purchasing the new clip, as it has some significant improvements over V1. We are offering both versions until our stock of V1 is exhausted.
For a quick and reliable way of attaching wire mesh to solar panels, nothing beats CritterBlok! Our favorite feature is that it allows for easy service of the solar panels without disturbing or re-attaching the wire mesh. Simply remove the reusable wire form that binds the mesh to the CritterBlok, and replace after service is complete.
Each CritterBlok clip includes a black, stainless steel wire form which binds the mesh to the stainless sheet metal clip. Wire forms can also be purchased separately and used on their own to bind two sections of wire mesh together– a reusable, tool-less alternative to hog rings or zip ties.

Sam Taylor –
We’ve used these on a couple of jobs now and love the serviceability of the clip. Not having to scrap materials when we service down the line is huge. They’re sturdy and sleek. Only complaint is the wire form is hard to wrap around the mesh depending on where the clip intersects the mesh. Overall recommend.

The Critter Blok clips are easy to use and leave a clean look. The best part is that they allow you to remove the wire mesh in order to service the array.
