Don't know that I've ever heard another term besides a stove or plate lifter/handle. I suppose the ones for the pots were "pot handles" and the ones for the grates or plates were "lifters."What is the real name for the thingy that lifts up these burners/plates?
Though, I suppose there's probably a technically-correct term that was originally used for those things. Lots of neighbors had them in the '60s and early '70s, when ducted heating/AC began to get installed everywhere.
EDIT: There once was a company called Summit Products (from Norton, OH) that made cast-iron parts ... and they called it a "lid lifter." (click)
