Window parts to simonton windows.
Hello, thank you for posting,
To further review for a replacement, we will need to see pictures of the pivot shoe that the coils attach to. Thank you!
Thank you for the additional pictures,
Your assembly resembles an older Simonton balance that is no longer made. We recommend converting to the 15-259 pivot shoe and Series 159 coils springs as a replacement. Please review the step by step video below regarding the conversion and additional products needed. Let me know if you have any questions.
The shoes are good, I have 25 in my cart.
I took 1 of my springs out to look for markings and the only thing I can find is "40" which refers to length I assume.
As far as weight, I weighed each window and wrote the weight down. Example, a 20 pound window sash wound need a 10 lb spring on each side to equal 20ish pounds of lifting power right?
And for the heavier 30lb sashes I have they have double strings on each side so I assume 2-8b springs on each side totaling 32 lbs of lifting power.
Hello!
The Series 159 coil springs are measured and can hold .5 pound increments.
You have two options for a 20 pound sash weight. First option you could use (1) 10.5 lb S159-10 on each side of the window to equal 21 pounds. The extra pound should not be an issue, but later down the line you may find the window is a little harder to close.
Second option, is doubling up the coils and using (1) 4.5 lb S159-4 and (1) 5.5 lb S159-5 on each side of the window to equal 20 pounds.
For the 30 pound sash, we suggest using (2) 7.5 pounds coils S159-7 on each side of the window to equal 30 pounds.
Please let me know if you have any additional questions.
