30" tilt window block & tackle counter balances

Hello,

Take a look and compare the specifications of the S795-30 channel balance to your assembly. Note that it comes with a 1-1/4" width T-lock shoe and uses a screw tab at the end of the pulley for installation. 

How to measure the length of the Series 795 channel balance.

Dimensions for 15-195

There should be a stamp code on your original balance channels that you'll need to choose the corresponding strength option for your replacements. Thank you! 

Thanks for getting back to us. I'd recommend double-checking the length of the metal channel, not including the T-lock shoe since this type of balance stamped with 28 would normally measure 28" long. 

Thank you for confirming. In that case, you may need 29E strength options for the S795-29 channel balances. To confirm, I'd recommend weighing your sash to confirm that it falls within the  28 to 32 lbs ranges supported by these balances. 

We're happy to help! Just let us know if you have any other questions. 

Your length and sash weight would correspond to the S795-29 (29C) channel balances, which support a sash between 18-23 lbs. Look it over and let us know if you need anything else.
