The frame is 1/2 square tubing and 1’ welded wire and They are approximately 4’ X 6’. You could use 1” electrical conduit and 1” chicken wire for squirrel proofing. The conduit comes in 10’ lengths...
ooh, thx for that. So, with the 10' electrical conduit, I could cut some off of it for legs, and they'd still be plenty long for my not quite 8' long rows.
I already emailed my gunsmith with the pic...but I actually could manage it myself, except for the welding part..I never graduated past a soldering iron.
Since it's in the 40's here this morning, I really should work on the door and window ends of my "gonna be a Texas Prepper's Greenhouse" project.
BTW, your flowers and yard in the background of that picture are quite beautiful.
