Window Balance Spring
A quick learner from San Francisco, CA says:

One end of the spring in my window balance has somehow come undone. How can I reattach to either the pulley or metal rod? The balance number is 2940.

I'm afraid the pulley cannot be repaired if it has been damaged in any way. You will need a new balance. I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.
