Window Balance replacement type

Hello,

I agree that your balances resemble the S770-28 except that yours appears to use a rivet at the top for an s-clip like our short 19-029 or long 19-030 s-clips to attach to. You would also need 28E strength options, which will support a window sash between 28-32 lbs. We can supply these balances but it will need to be a custom order. To get started, we'll need to confirm the number of balances that you need, with the minimum being two. Thank you! 

Thanks for getting back to us. We just sent over an order link and price quote for the balances you requested. I would recommend confirming that your balance channel measures exactly 28" long before placing an order. Also, please note that the s-clips are not included in the order link but they can be added to your cart to purchase with your balances if you need those as well. Take a look and let us know if you need anything else. Thank you!
