Sash balances (left and right) for Andersen double sash windows

Question

The lower sash cords broke. I need both sides replaced.

You'll need the 24-637 Andersen Sash Balance to replace the one pictured here. It is used for Andersen balances marked with a 623, 627, 631, or 637.

These will replace both sides.
