My window balance is labeled 27 4 Caldwell. It is 28 in long and 1/2 in wide. From looking at your site I think it is a s350 but I don't understand the 27 4 as a tension option

I'm thinking S350-28 with 2740 option but please check my options

Hello,

I agree that your balance resembles the S350-28 (2740). The determining factor would be how the specifications from our product page compare to yours. The 2740 strength option will support a sash between 19-26 lbs. as shown in the chart under the balance product description. Thank you!
