They had 12" unger and 12" HD brand for $1.63 and $1.33 respectively. I don’t use these, don’t know anything about them, don’t plan on using them in the future (other than my own house or truck/tractor). These do not screw onto a pole, they attach to those poles with the little detent on top (water fed poles or unger poles). ungers say they are stainless steel and the HD brand is plastic.
YMMV = Your Mileage may vary = it might not be at your local home depot
Just passing this along because I am an awesome human being and I know a couple of people here clean windows (although they probably use the uber expensive wizards only versions). Rainbows and unicorn farts to everyone.
