Jeff Layman formulated on Friday :
Can a stand-off be fitted safely to a telescopic ladder?

I have one which I bought (I think) a special offer from Tesco a few
years ago. Made from alloy, it works as either a flat wall stand off,
or can be located on the corner of a building. It just clips on to the
ladder via springs. I use it with my (very) heavy double extension. I
doubt it would work, or work as well with a telescopic.
