Hi the part number on the balancer is 11600-17 the window has two balancers. Assuming right and left. What is the corresponding part number for this? Thanks

See our 26-637. This is meant to replace old Andersen balances that include the stamp 623. This is a non-handed balance, meaning it will work on both sides of the window.
