Need coil style balancer replacement for damaged could

Question

Lower tilt out vinyl sash weighs -23 lbs and is 36" tall so probably need 35" travel. Old balance assembly has 2 coil springs as shown in picture. Springs are 1/2 wide with 5 stamped on one spring and #6 etched on other spring. Pivot shoe pictured checks 9/16" x 1 1/4" x 1" tall. No marking on spring cover except L S that I think means left side. Ready to buy S140-11 but could not confirm extension range on website.

Hello,

I would not recommend the S140 in this case but your pivot shoe looks a lot like our 15-111, which is designed to work with our 1/2" thick Series 160 coil spring and 15-150S cover. Take a look and compare the specifications to confirm. Thank you!
