I work with mostly duct board so I took a half piece of metal duct and had a different angle cut on either side to make transitions offsets and 90s. Then a few years back someone with a little initiative made one out of plastic and patented it. I was so ticked off. I paid them for my idea and have one in my truck.
I'm making a nitrogen gauge protector. I know its not symmetrical, but my nitrogen gauges aren't symmetrical at this point because I don't take them off the bottle. I'm going to weld some nuts onto it and screw two of them together on the gauge and hopefully it will help. I know this could all be solved by me taking the gauges off, but I don't.
Please bear with me as this is the first time I've tried to post a pic. Hopefully it is attached.
