Sash balance

Quick Learner from Bartow, Florida
Have several windows not staying up. This appears to be the culprit. The metal piece is 29" long without the end caps. One cap appears to be broken. The channel is 5/8" wide (outside to outside).

Hello, thank you for posting,

With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. 

If you have an undamaged balance shoe from the other side or a similar window that would be best to measure for the most accurate dimension.

You will need a 29" balance and the 28F stamp should translate to a 2860 stamp option that can support a 32-35 pound window sash. We recommend weighing the sash to confirm this range before purchasing. Please review and let us know if you have any additional questions!
