I've got a stabiliser from the dark ages, you know the weight thing for patio umbrellas that are filled with water or sand? Well its like that but bigger, has an adjustable hook on a threaded bar that clamps on to the bottom rung and two cut out slots for the bottom of the sides to rest against, would take half an hour to get it set up, thats why its never been used for years. I got it for nowt anyway.
