"One of our bestselling ladder accessories, the V Shaped Downpipe Ladder Stand Off fits most extension or combination ladders to give you much greater space when drilling into walls or painting windowsills. Designed especially to fit corner points or over guttering, the standoff allows additional arm room so you don't feel as though you are pushed against the wall. The 640mm wide span also improves safety as this helps to prevent your ladder slipping sideways while you are working at the top of the ladder. Heat treated for maximum strength and very easy to attach to your ladder, these aluminium stand offs will hold your ladder approximately 330mm clear off the wall. You can also use this on flat surfaces."
