Double hung window balance

Hello, thank you for posting,

Please review the style and dimensions of the 17/32" thick 15-199 pivot shoe. This shoe is compatible with either the 1/2" thick Series 160 or 3/8" thick Series 165 coil springs.

Please measure to confirm a good fit! Your original springs should have numbers stamped into the metal that indicates the weighted options needed. If there are no markings, please provide the weight of the sash to move forward.

Also review the compatible covers on the coil series product page. These assemblies are interchangeable on the left and right. Let me know if you have any questions!
