Builders First Source Window Balance

A quick learner from Austin, Texas says:
This spiral balance is from a BFS "Builders First Source" window. It has no identifying marks on the tube and is 29 inches long and 3/8 inches round. The end clip was damaged in a break in when the window was forced.

Good morning. Check out our S306-29 spiral balance. I believe this is what you want. If you are unable to determine what tip color you need, let me know the weight of your sash. Tip color represents the strength of the spring, so it's an important feature. You want to make sure your balances can hold up the weight of your window, but at the same time aren't so strong that you can't close it.
