The springs that have broken in my windows measure 3/8" with black tip and are 27 1/2" in length. I don't see a black tip spring in the 3/8 charts. The window weighs 17.4 lbs. Can you suggest the correct springs I should be ordering from you. Tip color and length.

Hello,
It looks like your balance may be missing the plastic housing tube that the older style version of these spiral balances used. I would recommend checking other windows in the house that use the same type of balances to see if one of them has an intact housing tube.
If so, you may actually need the (5/8") S600-27 spiral balances with red tips to support a sash between 7-29 lbs. Take a look and see what you think.
