Unique window channel balances

Question

Hello,

I have two different window balances I need.

1) 29" Unique 28-B-20 from previous post's you were sent with pic's this is a S380-29
this is a approximate 35" inch wide window.

2) 29" Unique 28-C-30 from previous post, you guy's said it is the same balance with option " 2830". This window is 51" inches wide. I will assume, the option is for the extra weight involved. Can you confirm these.

I agree, the S380-29 looks like the best replacement option in each case. A stamp of 28-B-20 corresponds to our 2820 option, and a stamp of 28-C-30 corresponds to our 2830. If you do not think this is right, I recommend weighing your sash on a scale to confirm its exact weight. We have a chart on the S380-29 store page you can use as a reference to pick the best option for your sash weight.
