Hi Dave,

This window balance can be replaced with either the S378-33, S380-33, or the S385-33. You'll need to measure the depth of the shoe to determine which series is the one needed to complete the repair.

You'll need to look for a stamp on the channel to select the option you need from the list shown on the website. Be sure that the sash weight falls between the weight range for the stamp.

There is a list below the product description with the ranges each stamp can support.
