The pivot shoes in our windows that I recently asked about (reference D116568) look like the 15-175 shoe shown in the photo posted by this customer. But in my case, there is no coil balance connected to the shoe. There also doesn't seem to be a spiral balance attached to any of the shoes I have examined so far. There should be some sort of balance mechanism attached to the shoe, shouldn't there? Do companies ever install windows with a balance? That might explain why our windows are so hard to open!!

Thanks for posting. You correctly identified the pivot shoe as our 15-175, which is meant to be used with our Series 152 spring. The coil spring is screwed to the side of the pivot shoe and the pivot bar would be our 26-405. Window manufacturers always have some type of balance system in their window so the sashes can operate. You won't need a charging tool to install them, since they just screw onto the shoe. |
