This instructable will show you how to make a (window) handle extension with a flexible joint for handles you can not reach easily.
Since my girlfriend is somewhat smaller than me and always had to use a chair to reach up to our upper window handles to open or close them, I made these for her.
They consist only of two cheap materials you can get in any hardware store, PVC-hose and aluminum pipe and optionally some tape to make it fit better.
We used them for over a year now on several windows and there is no sign of erosion (?) [please excuse my english] yet. Very durable, CHEAP (maybe 2-3 eur each) and REALLY easy to make. And - most important - it works really fine.
