Windows springs for sears double hung windows.

Hey there,

This balance assembly is a match for the Series 161 Roller-Tilt assembly. Since the housing is marked with a 7, you'll need the S161-07. The compatible hardware and accessories can be found tagged below.

In regard to the 8lb balance, is that the marking from the balance itself or the weight of the sash?
