No markings on coil for LB s. 1.5 in wide. 1/2 in or 9/16 thick. Looks like your s180 spring. Single coil. Need about 10.

Thanks for writing. This does indeed look like our Series 180 Coil Springs along with the 15-087 Housing Shoe. If there are no stamps on the springs, weigh your window sash. Give us that exact weight, and we'll work out what you need.

Thank you. You can go with the S180-8 coil spring. Take a look and let us know if any other questions come up.
