I have narrowed down my sach to S800-26 : 26" Series 800 Channel Balance, but I'm not sure what weight to select? Can you give some idea how to determine what weight I need. It's a double sash and I will be purchasing 2 sachs.
Thanks

First, we would like for you to measure the balance. With your stamping beginning with "26", it usually tells us that the balance measures one inch higher. Since your stamping does not correspond to our stamp options, the only way to decide which option to choose would be to weigh your sash on a scale and correspond that weight number to the weight range chart listed on the product page. If you would like for us to take a look at your balance and offer our input, you may forward us over some photos and we will be happy to review them.

Thanks for getting back to me!I'm not sure of exactly what you need to resolve my question. I took a couple pictures of both springs (good one & broken). The bottom window weights 22.6 lbs and name on the lock knob is Kinro?? Please let me know if you have a replacement sash. Thanks

Whoa, not so fast! That's not Series 800! See the wings you have on your balance? It can't be the same thing.

I'm pretty certain that your channel is wider than the Series 800, too. Measure the channel width. If it's 1/2" or 9/16", you have Series 380 or Series 385. You can measure the bottom shoe as shown below. The 1" shoe is for Series 380 and the 1-3/32" is for Series 385. Choose the one you need.

Then, measure the metal bar. I suspect the metal bar measures 27", meaning you need S380-27 or S385-27. Verify that. You'll want option 2640 for a 22.6 pound sash.
