Window balance hardware needed
Thanks for posting. This shoe looks like our 15-199. If you need new coil balances and don't have the originals on hand, this will get a little tricky. This shoe is compatible with both our Series 160 and Series 165 Coil Springs. The Series 160 Coil Springs are 3/8" wide, whereas the Series 160 Springs are 1/2" wide. I can't really say for sure which will fit your window best. I suggest you try and measure the thickness of the window track. That thickness might be able to tell us which coil spring Series will work for you. You will also need to weigh your window sash; that exact weight of the sash determines the spring weights you need to select for your coil springs. Let us know what you come up with and we will help you from there.
