Window Balance 27B
Hello,
Your channel balance resembles the S795-27 with a 27B strength option except that your assembly uses the 15-272 bottom fitting for installation. We can supply replacement balances with this shoe attached through a custom order.
To get started, we'll need to see a photo of the metal clip at the end of the balance pulley cord that is used for installation. Also, please note that the minimum order would be two balances since it is important to replace both sides at once to ensure that the sash is equally supported.
Thanks for getting back to us. We just sent over an order link and price quote for the balances you requested. Note that the 27B strength option for these balances will support a window sash between 11-17 lbs. Take a look and let us know if you need anything else.
