Window balance 26 4 bsi

Hello,

We'd be happy to look into this for you, but the stamp code only indicates the strength of the spring. We'll need to see photos of both end fittings and the pulley clip to compare to our inventory. Thank you! 

Thanks for getting back to us. We can supply your replacement balances, but it will need to be a custom order due to the extended travel pulley system and unique combination of end attachments. Note that the metal channel should measure 26-7/8" long without the end fittings. If so, we'll just need to know the number of balances you need, with the minimum being two.
