Parts needed

Thank you for submitting your inquiry to our discussion board.

Can you please send us a picture of the top attachment on this balance?

Thank you for getting back to us with photos of the top attachment on this balance. 

You will need either a Series 351 or Series 390. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your old hardware to determine the best match.  

Please confirm the length of the metal channel, not including the nylon attachments at either end. If it is 18", then you will need the S351-18 or S390-18. To know what stamp option to select, obtain the exact weight of your window sash. You can then match that exact weight with one of the stamp options listed on the product page. 

Thanks again for your inquiry.
