Tyre was from a pet shop for dogs to chew
I use it to rest/hang/slide the pole on the edge of the gutter. F16 was brilliantly light but thereby was its problem. I have since fitted Glyns looped hose and although the c/f copes it gets a bit scary at height. For most jobs I use Omni alu which have a better "feel". Glyns tools also have different and better angles than the B&Q stuff.
What I would like to see developed is a heavier duty c/f 2.5" dia locking section modular, with an internal liner that would take the hammer that these tools get. But then its just as easy to use the alu section.
Just a note to all you newbies, its hard blxxxy work and some, thats why using the right tool makes the job slightly easier.
