Help Identifying Non-Tilt Window Channel Balances

Question

Hello! I need some help identifying and replacing my non-tilt window balance. One of the two balances recently fell down the window frame as I lifted the window to open it (vertical up/down opening, not a sliding horizontal left/right). There was a broken cord/string inside that fully came out of the balance when I removed the balance from the window frame.

If it's helpful, the house was built in 1994; not sure if they are original balances, but have been here at least since I bought the house in mid-2017.

Total length: 22"

Metal balance width: 1/2"

Top guide and bottom shoe width: 7/8"

Markings: 20 3 KQ CALDWELL

Thank you in advance for your help!

Hello! Thanks for reaching out to us.

We're happy to look into this, but we would also like to see an image of the inside of the balance’s metal channel, where the innerspring connects to the pulley mechanism; this connection is located in the middle of the channel.

Additionally, can you measure the bottom shoe as shown below and write out what you get?
