Requesting help to identify replacement window balances.

Handy Person from Indiana
Hello - Hoping you can assist with identifying replacement window balances.

Manufacturer: Jordan, Series 25 "Thermal Barrier", aluminum single hung windows. They are about 30 years old.

The marking on the balance is: 28 3 FK Caldwell (see attached picture).

The length of the metal portion is 29 inches.

Included pictures to assist in identification.

Thank you for your help.

Regards,
John

Hey John. It looks like you have either an S351-29 or S390-29. The only difference between these two channel balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement. See the diagram below for reference. Measure the depth of your existing balance's shoe to see which matches best. For a new stamp option choose 2830.

Comparison of the S351 and S390 balance shoes.

Thank you for your assistance. I ordered S390-29. They were easy to install, and the window now works fine. Will be ordering more in the future.
