Hi Ariel. This looks like a 15-111 Pivot Shoe, which uses either our Series 160 1/2" thick Coil Balances, or our Series 165 3/8" thick Coil Balances. Measure the thickness of your old coil springs to determine what Series you need. |

Hey Ariel. If the springs are a 1/2" thick, then it certainly sounds like you need the Series 160 Coil Balances to go with the 15-111 Pivot Shoe. You'll have to select a spring weight for each coil balance. Look for stamp codes on the springs that designate this. If there are none, or you are uncertain, obtain the exact weight of the window sash. Give us the exact weight, and we can work out what you need. |
