I need to replace a window balance assembly for my 24 x 30 single hung vinyl window. The number on the assembly is Caldwell 19 4 GL. I am enclosing four pictures of the broken assy. Hopefully you can help me.

Thanks,

Frank

See our S351-20 or S390-20. The only difference between these two balances is the depth of the bottom nylon shoe, so compare both with your old hardware to see what matches best. You'll need a stamp option of 1940.
