Thanks for contacting SWISCO. Give our 15-177 Pivot Shoe a look. This shoe is compatible with the Series 152 Coil Springs. 

The stamp on your coil springs suggest the S152-8 may be the right choice for you; but the best way to be sure is to weigh your window sash. The coil balances are distinguished by the amount of weight they are meant to support. For instance, a single S152-8 unit is meant to support 8 lbs. If your window weighed 16 lbs, you would want an S152-8 on each side of the window. 

If you do weigh your window and that precise measurement turns out to be something different, let us know and we'll find what you need.
