Need BSI Window Sash Balance Identified

Hi there!

Thank you for reaching out to us. We can help supply a replacement for this balance but it will have to be a custom order due to the heavy-duty stamp on the metal channel. I'll just need a few pieces of information to get this moving for you. Can you measure the bottom shoe as shown below and tell us what you get? Can you also confirm the length of the metal channel? 

Comparison of the S378, S380 and S385 balance shoes.

Thanks! What I will do now is email you a purchase link for (2) Series 385 balances with a 27" long metal channel and 26DS45 stamp. You can use this to place an order on our website. Please note there is a 5-6 business week lead time. 

You may also want to confirm that your balance's metal channel is also 27" since custom orders are non-refundable.
