Window balances needed

This window balances is a Series 795 Channel Balance. Since this one is marked with a 36D, you'll need the S795-36, with a 36D stamp option.

The shoe on the balance is the 15-194 1" T-Lock Shoe, which is sold separately from the balance. The replacements will come with a 1-1/4" attached but they are fairly easy to swap out. There is a video tutorial, tagged below this thread, with instructions on how to do so.

For the remaining balances, you'll need to be sure to check the top attachments (to confirm that they also have  screw tab), the length of the channel, and the width of the shoe.

Please let me know if you have any questions you might have!
