Window balance and shoe

Thanks for contacting us! The channel balances you have here appear to be the S770-30 with a 30D stamp (supports a 24 to 29lb sash) and the S770-32 with a 32D stamp (supports a 25 to 30lb sash). I am confident that these are what you need but you'll need to be sure to do double check the lengths, the stamps, and if the balances screw in at the top of the window channel.

The pivot shoe can likely be replaced with the 15-129 Pivot Shoe. Carefully review and compare the dimensions below to confirm that this is the right replacement.
