Good Morning,
The stamp provides the length and strength of the balance but not the series.Can you send us photos of the attachments on your balance? (unless you are positive your attachments match up to the S351)
You have Series 385-30 with the option of 2990 which is a custom balance. Can you weigh the sash and get back to me. You might be able to use a stock balance. You can weigh your sash on a scale like a bathroom scale.
Hi Paul,
The sash weighs 30 lbs.
I watched the video on removing and installing balances. It appears that mine is not installed that way. If you notice the hook on the terminal end, that attaches to a slot in both jamsand the bance sits in the frame of the sash. It does not look like the lock out clip is used.
Thanks
Hi Paul,
My bad, saw a different terminal end and was incorrect. Your video and directions are perfect. Hope to see what I need to buy soon.
Hank
Hi Paul,
With the info I gave above, please let me know which channel balances to order.
Thanks
Hank
