New sash balancers for eagle windows
Hello,
Your balance resembles the S770 except that yours uses a rivet at the top for an S-clip, which we can supply through a custom order. To get started, please confirm the length of the 20C and 19C metal channels.
As for the pivot shoe, take a look and compare the specifications of the 15-129 to your part. Thank you!
Thank you for confirming. The stamp codes for our balances are a bit differe. The 20" long S770-20 balances would have 20C strength options to support a sash between 14-18 pounds. The 21" S770-21 will have 21C options that will support the same 14-18 pound weight range. I'd suggest confirming your sashes fall within the supported range. If so, we'll be happy to send over order links and price quotes for both sets of balances.
