I know this is a woodworking Q&A, but since googling to the best of my keywording skills didn't work, I'm trying my luck here.
I'm trying to build a home office desk for myself, with a metal frame, but I'd like it not to be a one big welded piece of frame. I found this dinner table in a store that had this clever joinery, which could "easily" solve my problems.
Anyone knows what it's called?
