Piffle - just three feet?
I briefly did garage door installations, and we were working one job in a wood drying barn about an hour north, at the same time the fire sprinkler contractor was installing the sprinkler pipe. Two guys, each with a six foot pipe wrench: one set his wrench on the pipe or fitting that was being held still and stood on it; the other did the grunting to get a good tight fit. They traded off each time between standing and grunting.
But I tease: my longest pipe wrenches are 24 inches.
