Channel Balance

Question

Window is a PGT 8100-SH Series.  It uses a #2965 DX channel balance. The channel balance measures 30" long.  The sash weighs 37.2 pounds.  The problem is that the windows are extremely difficult to close.  You have to put your full weight behind closing the window.  Is there a different channel balance that could be used that would provide less resistance and make it easier to close the window?

Hello,

We can supply your replacement balances but it will need to be a custom order due to the length, extended travel pulley system and unique combination of end attachments. The 2965 stamp code indicates that your balances were calibrated to support a sash between 35-39 pounds. Since your sash falls within the supported weight range, that leads me to believe that the originals are most likely older and in need of replacement. Also, please note that these balances come with 29-7/8" long metal channels, not including the end fittings, which should match your original assemblies. We just sent over an order link and price quote for two replacements. Take a look and let us know if you need anything else. Thank you!
