Hi Shining,
You can get a detachable aluminium gooseneck for your pole. If your pole has a plastic screw end on it, we supply a G-Fit (registered design) aluminium gooseneck that will fit all poles (with an end screw fitted, one can be bonded in if needed) and will also allow brushes to simply screw on the other end. This gooseneck only weighs about 130gms as well so it does not add too much weight.
