Custom balance

Hello,

We should be able to supply the S770-33 balances you need with the 15-044 pulley attachment. To get started, we'll need to confirm the number of balances you need with the minimum being two. Also, make sure to confirm your balance installs with a screw at the top of the channel. Thank you! 

Thanks for getting back to us. Before we send over your order links, I want to confirm the strength option for your replacements. We generally recommend sticking with the code used with your original balances, which shows 33G. 33G balances would be calibrated to support a sash between 37-40 lbs.

These balances max out at 33I, which will support a sash between 43-45 lbs. I'd recommend double-checking the weight of your sash to confirm if one of the strength options we can provide will work for your application.
