It fits Sekisui's 6 type screen door. The screen door of the screen door which was manufactured twenty years ago was broken, and when I searched, I found this product at another company site. Although the main body price was cheap, there was a shipping cost, so buy it looking for the same thing with Monotaro. Although the shape of the part is somewhat different, the size was perfect and it was fixed without problem.
It was good that there was a similar thing because it was a dedicated roller. We would like to ask for a lineup so that sash can be replaced at the same time if there are instruments for preventing the rail from falling off (resin).
