You likely need the S351-35 with the stamp option 3430. Make sure the S351 balance attachments match your balance attachments. For close up product pictures of the attachments, see 19-002 and 15-002.
If you need help or those balance attachments do not match your existing balance, please submit some pictures of your Gapco window balance here for us to review. |
