Thule Omnistep 12v step, in good working order, replaced it with a double step for little legs, its the 500 wide model that seems to not be made any more just 440's and 550's according to Thule website, see link, full instructions included as well as supplied switch and fixings, works of my Sargent EC50 so switch was not required, previous owner lathered the moving bits in grease that my degreaser cant shift so coming ready protected from elements, postage extra
