Hi Tony
Yes the ends are tapered so no clamps required or screwing up joints, just a simple push fit.
I have the alloy poles and I know what you mean about seizing up, but they dont get used now, they were ok on straight work, but if you were working
above 20 foot at any significant angle for some time it became a bit labour intensive.
With these poles I can pull up and be working within a couple of minutes that includes taking vac off van and fitting hose.
Price wise you have to purchase minimum 5 as I said earlier, I got more as I do some high work, but it works out at £54 a section + the inevitable + del,
but for me it has paid off easily. Good company to deal with also.
Steve
