Could you please recommend a replacement for a balance stamped "20 4 EQ CALDWELL"? I do believe it's a 21" Series 385, but I'm not sure what option (2019 to 2050) to choose. I'd like to replace both balances. Thank you

I have several windows with this size balances that need replacing. The windows are made made by Viking windows who no longer are around . Place I just to buy them at is no longer in business. Any help would be greatly appreciated. Thanks.

mine are single hung windows, over twenty hears old. One is stamped 20 3 KP Caldwell, and the other 26 4 LP Caldwell. I'm looking at 380 and 385 as likely clones but can't decide which. What is difference?

Based on your channel balance stamp, you'll want to select spring strength option 2040. Two of those should be able to carry a 15 to 23 lb sash.

my channel balance is 22 inches long and 9/16 wide. It is from an All Weather window that is about 40 years old. Do you make a 22 inch long balance or will the 21 inch work? I am an un-handy homeowner- Help! Thanks Bob
