Spiral balance help
Thank you
Hello,
You appear to have a hurricane window with non-removable sashes. The nylon pieces on the face of your sash are face guides; don't remove them, or they will break. You'll need (5/8") S500-18 red tip spiral balances. Raise the sash and look under it with a light to see if there is a bracket to catch the bow tie at the end of the spiral. Our 75-005 charging tool is very helpful in installing this balance to the sash bracket. Thanks for posting!
If you don't see a bracket attached directly to the bottom of the sash, it is most likely on the inner corner. These are not easily replaced since the sash is non-removable. If the brackets are still intact, you can just reattach the new balances to the brackets. You can see some examples in our selection here.
