Installation Guide
Recommended Tools for Installation
Slicktools Bender (or Long Metal Bend Bar + Saw Horses)
Wire Mesh (verify correct size)
CritterBlock Fasteners
Shingle Cutters (*cutting wire mesh lengths)
Diagonal Cutters
Impact Driver
5/16” Driver
Self Drilling Screws w/ Washer (PART # 11709-04007 from Fastenal)
Roof Anchors, Harness + Fall protection
Tape Measure

Step 1: Measure the Gap
Measure the distance from the roof surface to the bottom of the array. Take measurements in multiple locations as the distance may vary.
Set up anchors and ropes to ensure a safe critter guard installation.
Step 2: Bend the Mesh
Bend the mesh to the desired height for a snug fit. The installer can use a ~12’ bend bar but we prefer the Slicktools AG Bender.
Cut the mesh into easy to manage 10’-12’ lengths.
Bring all the material + CritterBlok to the roof.


Step 3: Pre-Install the CritterBlok Clip
Reach under array and pull clip forward onto the panel frame. Once engaged, while still holding the clip in place, push the main clip forward until flush with the panel.
We recommend pre-installing the CritterBlok around the perimeter of the array where no rail exists to self tap too.

Step 4: Cut Mesh Around Obstacles
Using the diagonal cutters, cut mesh to avoid obstacles to include a notch where the CritterBlok is located. Continue around the perimeter and attach to either rail or CritterBlok as the installer continues.
Step 5: Install Mesh & Attach Wire Splice onto Main Clip
To fasten the mesh to the CritterBlok, press mesh against faceplate with one hand and pass wire form through the mesh and secure into final position.
The installer may need to move the CritterBlok laterally to “line-up” the mesh holes with those of the CritterBlok.


Step 6: Joining Two Pieces of Mesh Together
The wire splice can also be utilized to couple two pieces of mesh together. This eliminates the need for zip-ties or other methods of connecting two pieces of mesh.
