I need four balances. Photos below. They measure 31" long X 9/16" wide. The townhome was built in 1985 by Ryland, in the kings grant section in Marlton. I don't know the window manuf. Number stamped on balance is 3030. Please let me know price and availability. Thanks, Bob

Hi Bob, thanks for submitting a photo. We need to see a couple close ups and different view angles of the balance attachments to determine which series you need. Can you take a couple more images of each end and upload them here? It is the attachments that determine the replacement balance series.

If you would like, you can browse through our channel balance catalog section to see if you can pin point the attachments yourself. If you see your attachments, or something close let me know and I will help you determine what you need to order.
A quick learner says:
the first two photos show one attachment that is still not cracked. the third photo shows a cracked attachment that is on the opposite end. I hope this helps. Thanks

The replacement balance you need is the S371-31 with the stamp option of 3030. Take a look at SWISCO product 18-124P if you need top sash guides (these should match what you have).
