re post*1, this thread.....Already have a pair...they perform better than shown. Can hook them [pair] to support a walk plank, use one as a shelf, or roof edge to stand off gutter. The various inclines provide a range of leveling [uneven ground], the flats match stair risers and landings. In tandem, they can work like adjustable parallels.
Were found on used market, and more come up often enough.
