I got these two wheel weights with one of my Bolens Power Ho's. Note that they are similar, but not identical. I have not weighed them to be sure, but I suspect that the one on the left weighs more than the one on the right because it is significantly thicker. The one on the right has a stepped edge on the back side, unlike the one on the left.
So, are these actually Power Ho weights? Are either one? (The one on the right seems to nest into the rim nicely.)
