Flanking a workbench, with a top over it with a light mounted and then a pegboard back wall between them over the bench top.
Would make a nice little work station.
I'm kind of liking this idea, but the real deal is what to put in them; the 12X12 "floor plan" is somewhat limiting. Hmmmm... A third unit, if long enough, could go horizontally between two used as "pillars" as a locking "bookshelf"...
I would use them as lockers for work clothes. Change at the shop, no need to wear greasy dirty clothes in your truck to and from work.
At a workplace that is not a bad idea, but these are for home use, so somewhat limiting for that use
weld some shelves in them and use it for spray can or hardware (in 12" deep plastic bins) storage
Spray paint storage I've got well covered in a shelf over my pick-a-nut selector and the machine screws bins. It even has an "earthquake bar" to keep them there in the event... Fastener hardware (and nails) I have covered (see below)

I store gallon paint cans in them. It beats stacking them, which frequently ends in tears...
House paint I do stack, but I use the 4 can carton/trays to hold them, so that is fairly stable up to about 4 ft high, especially if you have 2 stacks and put a thin sheet of ply or even cardboard between the layers about 3 ft up to stabilize the stack.
They look too skinny, but would golf bags fit in them?
I doubt the 12 X 12 would take a golf bag unless a 40's/50's skinny bag, much less the about 10" opening between the angle iron front frame. I'm not a golfer anyway so a moot point in any case.
I did something a bit different with the lockers that I had gotten for free out of a Sports Clips that was being remolded. Mine are different than yours as i was able to cut them in half and make a base for a work bench out of them. I made wooden shelving in them to store spray paint, paint cans, oil, etc..
I like that but something look out of whack, the installed lockers look wider that the starting pics?
I really like those wide, low ones. Looks like a useful size.
I have passed up a lot of 2 or 3-high by x-wide locker sections at auctions because I couldn't (still can't) think of a good use for them in my workspace. If I am going to take up wall space, it had better provide me a great deal of utility to do so.
Exactly why I started the thread!

I like the idea of a locker, but I want it to be worthwhile! I have nothing invested except a short trip to go pick them up, and the time I've spent completely dissembling them to flatten out dings and kinks and such (My homemade sheet metal tongs have been doing some overtime...), and to prep them for painting.
I'm thinking about removing the middle divider and making shelves so they go 2 ft wide, and it occurs to me making them deeper would only require two new sheet metal sides, and a top. the real value in the find are the doors and door frames with all the hinge/latching hardware.
