4 with square pads, one with a bow support. 5 in total.
All are approximately 5'2" tall at their lowest with 18" of travel. They call them 6 footers, middle of range I guess.
All operate smoothly. Could use a coat of paint, but are 100% solid.
Hard to find a price on these new in Canada, but near as I can tell they're over 300 USD EACH, as seen in manufacturer picture.
That'd make it $440 Canadian each, plus tax... which seems insanely high to me but that's the price I find, so I divided it by 3.
