Channel balance

Hi Tom, thank you for posting,

Your balance resembles the Series 770 plain 9/16" wide channel, but with the 15-014 knife shoe attached instead of the terminal clip. We can provide this configuration via a custom order. It also appears that your balance installs at the top with a S-clip like the 19-029 or 19-030. We can add a rivet at the top for this type of installation. 

A 35" 35C stamp balance can support a 22 to 27 lb window sash. We recommend weighing the window sash to make sure this range matches up. 

How many balances are you looking to purchase? For custom orders there is a minimum of (2) required. If you would like to move forward, let me know and I can send over an order link with pricing for your review.
