Tilt window balances

Question

Need to replace my tilt windows balances balances.  The length is 28".  I took a pic of markings. (11/2) UNIQUE 27-F-60.  Do the numbers refer to the weight load.

Your window balance has a terminal clip, like our Series 770 Channel Balance. Since your channel is 28", you'll need the S770-28.

I believe you can use the 28F for the stamp option, but it would be advised to weigh the sash to confirm that the weight is between 32 to 36lbs.
