The flashlight and the extinguisher want theirs, too.
I've often thought about making them for the shop extinguishers (6 total), but in the interest of being able to quickly grab them if needed, I thought the best thing was to leave them on the plastic hanger/clamps.
As for the maglites... interesting story. About 12-14 years ago, Maglite use to be sell powder-coated metal clamps. Then all of a sudden, you couldn't find the manywhere and all that was offered, were the newer style, all plastic clamps. And we all know these are ****, that break in cold weather, and are just no substitute for the previous style.
Well, about five years ago I stumbled onto a guy on e-bay who was selling them. He claimed in his auction description, that he worked for the company that made them years ago for Maglite, and had found a stash of NOS in their plant. So I ordered a pair to see if they were what he claimed. Well, they were! So I ordered about a dozen more from him. I've got at least six Maglites hanging on the walls in my garage, at least one mounted in every vehicle I own, and gave a few to some of my buddies. I've since looked for the guy again on e-bay and can't find him anymore. Oh well.
