Mi window series 1555 window balance

Hello! This coil balance assembly appears to be a match for either our Series 161 or Series 210. The only difference between them is thickness, so you will need to remove the original and measure it to verify the best option.

I'm afraid we don't sell these in that size. The Series 161 is 9/16" thick while the Series 210 is 7/8". Could yours be 9/16" instead?

Great! Please let me know if we can be of any further assistance.
