Stacable constant presser balance

Take a look at our 15-111 Pivot Shoe. This looks like yours, but check to confirm. This shoe is compatible with our Series 160 1/2" thick Coil Balances, as well as our Series 165 3/8" thick Coil Balances. Compare both thicknesses with your old springs to see what matches best. 

To know what spring weights to select, look for stamp codes on the springs themselves. If there are none or you are uncertain obtain the exact weight of your window sash, and we can work out what you need.
