Hello!
This looks like a Simonton coil balance which isn't made anymore, but take a look at our 15-259 pivot shoe and Series 159 coil balances. The video below will walk you through the installation process and the parts we recommend.
If you're not sure what coil weight you need, you'll need to remove and weigh your window sash. Then, you'll divide the weight by the number of coils on both sides of the window to determine the correct strength option.
All orders can be placed directly on our website at your convenience. I'm not sure what coil weight you'd need, though. If you can give me the precise sash weight and the total number of coil springs in the window, I can work out what you need.
If your sash weighs exactly 13 pounds, you can use (1) S159-6 6.5 pound coil spring on each side of the window. This totals 13 pounds of overall support.
As long as the spring weights are within a pound of your sash's actual weight, this setup should work for you.
No need to apologize! I've listed the parts mentioned in the video I linked you to previously on this page. All orders can be placed directly on our website or by phone to our customer service department at (888) 991-1929. Their phone hours are 8AM - 4:30PM EST.
Let me know if you have any questions!
It was my pleasure. Thank you for your business! Let me know if you need anything else and good luck with the repair!
I'm glad to hear your windows are back in action! Regarding the top sashes, the replacement process will be the same as shown in the video I linked you to before. However, if you need to make a new cut out to remove the pivot shoe, the placement of the cutout will be different for the top sash. If your window already has a cutout, you won't need to worry about making a new one.
Keep in mind, if the top sash is a different size from the bottom one the coil strengths will be different. If that's the case, we recommend weighing your sash and then divide the weight by the number of coils on both sides of the window to determine the correct strength option.
Let me know if this makes sense or if you had any questions.
Hi. The upper sashes weigh 11.5 each. If I divide by two that equals 5.75 so would the
5.5 lbs Series 159 Coil Balance be the correct part for the upper sashes?
And Will the Coil Balance Pivot Shoes 15-259, 3/4" Coil Single Supports 15-255, and the 2 1/2" Pivot Bars26-083 fit the smaller 5.5 lbs Series 159 Coil Balance on the upper sashes?
Yes, if your sash weighs 11.5 pounds and has 2 springs total in the window you can use one S159-5 5.5 pound spring on each side of the window. This totals 11 pounds of overall support; so long as the spring weights are within a pound of your sash's actual weight, this setup should work for you.
If you only have one coil spring, you'll need the 15-255 Coil Single Support. I'm not sure I understand your last question, however. The 26-083 pivot bar is fully compatible with the 15-259 pivot shoe.
