Broken Window Channel balance

Handy Person
I am trying to find a replacement part for a window channel balance.  The markings on the part are B.S.I 22H  I assume  this is a 22" long with and H load rating?  it seems to be ~9/16 wide by ~1/2" deep, It has a tab on a string that attaches into the block that mouns to the bottome of the window.

Hi there!

Thank you for contacting us. We're happy to look into this. Can you show us the attachment at the end of the pulley cord? We'll need to see how the balance connects to the pivot shoe. Can you also confirm how the balance installs at the top of the window track? Lastly, can you weigh the window sash on a scale and tell us the precise weight?

It appears your balance uses the same terminal clip as the Series 770, which is designed to be screwed in at the top of the window. A pair of balances with the 22F stamp will support a sash weighing 27 to 30 pounds. However, we recommend getting the exact sash weight to confirm it falls within this range. If the weight exceeds 30 pounds, please let us know and we can go from there. 

Do you need the pivot shoe too? If so, you can start by taking a look at the 15-129 but you'll ultimately have to remove the old one and compare the specifications to see if they align.

Please let us know if you have any questions.

Thank you for letting us know. We can supply the S770-22 with the 22H stamp via custom order. A pair of balances with this stamp will support a sash weighing 34 to 37 pounds. 

I'll email you a purchase link and price quote for (2) that you can use to place an order on our website. Please note that there is a 5-6 week lead time.

Let us know if you have any questions!
