Cleaning French Windows in Half the Time: MULTI-SQUEEGEE by Sorbo
If you've ever been mystified by how the channel end clip is removed or inserted, this video is for you. Part of the secret is to relax and not worry too much about it. The end clip is a tough little bugger, and the rubber is too. So take it easy... feel free to push, pull and bend this way or that to make it all come together... and don't forget, a little lubrication never hurts. But please, only use water.
