- 2 x 96" furring strip (home depot will know what this is)
- 2 x 4pcs galvanized corner braces 1.5"
- 1 x 4pcs mending plates (should be very close to corner braces)
- 1 x 2' x 4' plywood sheet (they are precut in little bins with all the plywood)
Step 1. Measure and cut furring strip
- For a 6gpu frame I would do 22" instead of 20" for the long rails like you see in my pics.
