I bought a clothespin hop to attach to the sweep window on the first floor. Vertical storage type is not attached because there is a shutter door pocket on one side. Therefore, one of this swing thing is ordinarily attached to the wall, and the other is attached to the door pocket and it is used at 90 degrees (in the state where it is stored normally). The thing was firm and it was very cheap. Since screws are not attached, I bought wood screws and washers that fit the size at the home center and attached them. As one is a different usage from normal, I do not know what will happen if a load is applied, but I am satisfied so far.
