Window Balance 34 9 CX CMC 4

Question

I'm trying to determine which part number balance to replace on my Kinco window balance. The channel shows a part number of 34 9 CX CMC4. The length of the metal is 35" and the width is 1/2".

Start by looking at our S385-35, this may be a good match. I would also recommend weighing your sash on a scale to confirm that you get the right spring strength option.
