Thank you for posting on our discussion board. We believe you can use our 18-036 top sash guide in place of your current one. This part is used with the Series 800 balance. Your screw hole measurement should match up to ours. Measure it to confirm this information is accurate. As for your balances not holding the sash up, I noticed you recently purchased the S800-30 with a 29B option, which supports a sash weight of 8-14 pounds. Did your original balance have the same stamp option as the replacement? Do you happen to know the exact weight of your sash? Please get back to us and let us know. |
