Brush Adapter

This is supposed to be an adapter connecting a 5.2m long pole (YK new aluminum roller pole) from Yoshikawa Sangyo Co. Ltd. (https://www.monotaro.com/g/00491803/) and a deck brush PET-18 Spare from 2989.jp Plus (http://www.2989.jp/product/arau/4903180176199/).
I made this for brushing my house wall by utilizing a long pole purchased long ago.
It worked for me and I would like to shere it with the community.
