For the 23" balance, see our S600-23 with a Red Tip option. For the 21" balance, see if an S600-21 with a Blue Tip option supporting a window sash in the weight range of 10 through 29 lbs is what you need. For the pivot shoe, the design looks a bit more like the 15-015, but double check your old shoe's dimensions to see. |
