Hello, thank you for posting,

Please review the style and dimensions of the 15-228 pivot shoe as shown below. If the coil spring measures 1/2" thick, see the S160-07 that can support 7.5 pounds of weight. Together with the other side, the total sash should weigh 15 pounds.

Also see the compatible 15-150S spring cover. Let us know if you have any additional questions!
