Simonton windows - need new coils

The Simonton shoe in your assembly can be replaced with the 15-111 Pivot Shoe (the heavy duty version is the 15-191). This shoe is compatible with the Series 160 Coil Balance.

To confirm the correct coils for your assembly, you'll need to examine each of them for a stamp/marking that will indicate the amount of tension the springs should hold. If there aren't any, you'll need to obtain the exact weight of your sash and divide that number by the total number coils in the window (in your case 4).

To replace the cover you'll need the 15-150D 1/2" Coil Double Support; the black rubber piece is the 15-148 Bumper. Should you decide you also need to replace the pivot bar, this shoe is compatible with the 26-241 Pivot Bar.

The coils seem to be pretty damaged, so I have doubts you would be able to reuse them. If you do not believe the shoe or the pivot bar need to be replaced, then you should be fine without having to replace them but you'll need to use your discernment to determine that.

Since the sash is 14.5lbs, you'll need (4) S160-03 Coil Balances to repair this window; (2) for each assembly.
