"I found this angle bar with chains attached. It’s about 6 feet long. Does anyone know what this is used for?"
A: "Looks like a brush cutter chain guard. These hang down off a brush cutter or “bush-hog” type of attachment to stop bricks stones and large tree debris flying out and causing injury. The holes in the angle iron would allow the length to be bolted to the machinery."

Hey Izi? When you're posting these, make sure you scroll down the thread to the right answer to what the OP answers to as "Solved!" on Reddit r/whatisthisthing. u/leelee_nyc had the correct answer: Gaggenau Vario steamer (model VK230114).
Not a double boiler. :) Just a polite fyi.
Notice the steel wheels. Back when warehouses had hardwood floors multiple workers would use one these to drag palleted goods short distances, like when one pallet needed to be jockied out of the way to fetch another pallet.
Also used by truckers in the back of trucks.
