Waste of time trying to use an extreme pole to shut windows, they're not strong enough for that purpose. I only use to use extreme 44 on higher work but I must admit I'm addicted to using extreme 22 and 25 now on most jobs. Much quicker raising and lowering the poles, less fatigue, more work achieved in less time, ......love extreme poles. Keep a spare SLX for places where I know windows might be open and may have to push them shut with SLX pole so extreme stays in van on them jobs.
