Hello, thank you for posting,

Please review the style and dimensions the 17/32" thick 15-199 pivot shoe. Compare to your original to confirm a good fit! This shoe is compatible with the 3/8" thick Series 165 or the 1/2" thick Series 160 coil springs.

Alternate view of 15-199

You will need to measure the thickness of the original springs to confirm the series needed. From there, match up the number stamped on the coil to determine the correct weighted option. Also review the compatible cover on the coil series product page.

Let us know if you have any questions!

The shoe I have is 1-1/4 × 1-7/16. It appears to be almost 9/16 thick or just under.
The springs all say #4.0. 35". They are 3/8 wide.

Thank you for confirming,

Please see the S165-4 coil springs along with the 15-205 triple support cover. With three springs on each side, the total weight of the window sash should weigh 24 pounds. Let us know if you have any additional questions!
