We are looking for some old MW window balances. The shaft (gray) is 27 1/4" long, the spring is 13 7/8" long, and the other parts are in the picture. Please advise if this is something you have?

Hello,

Your old-style rod balances are no longer available. You can use the S795 channel balances as replacements as long as your spring measures 1/2" in diameter. See the video below to walk you through the full conversion process. Thanks for posting!

You'll need to locate an undamaged balance to measure as shown at time stamp 1:37 in our conversion video. Your balance should measure in 1/2" increments, which you would round down to the nearest inch for the S795.
