I work for a local school district and have a lot of OLD Traulsen reach-in ref's and frzr's that the shelf bobbin rivnuts have pulled out of their walls. Just kinda proud that I fabricated these and enabled the units to continue service without being "afro-engineered". The original interiors are 5052 "dead-soft" aluminum, and the new reinforcements are fabbed of stainless steel with "bottomed" aircraft rivnuts just like original ones....only now they can't be pulled out of the soft aluminum. I believe a lot of my new True units use the same 10-32 threaded bibbins and rivnuts. Hopefully someone else can use this idea.
Whole sheet of SS purchased from local "Ace" hardware.
Same sheet, pre-drilled and cut into individual and dual-rivnut versions.
