35" Series 350 Channel Balance

I have single hung dual pane PGT aluminum windows about 8 years old that have balancers that are failing explosively flying upward and flinging pieces out as they "blow". As best I can tell by your pics and an entire spare balancer I found when I bought the home, mine are similar to your 35" Series 350 Channel Balance but I can't determine the sash weight range. The channel has "86 34-9 AC5 CMC" imprinted on it but no other identifying marks. The metal channel is 9/16" wide X 35" long. What is your replacement? Thanks!

Good morning! Stamps ending in "9" use an old type of designation that has gone out of style. One of the existing stamps for the S350-35 may work, but you will need to weigh your sash and refer to the chart shown on that store page to confirm the proper match.
