Balance ID for aluminum non-tilt windows

Question

Hi Swisco,
Happy holidays!
I'm in need of help identifying these windows balances. The window doesnt stay open but i was able to remove the sash to access the 4(2 per side) balances which were all broken. The sash was quite heavy and I think thats why it needed 4?

I've attached images of the top and shoe as well as the manufacturers label. The stamp on the metal channel reads 3090 EL 34 and is 31" long in total.

Thanks so much!

See our S380-31 or S385-31 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe, so compare both with your old hardware to see what matches best. You'll then need to choose a stamp option. Your old stamp option of 3090 is from a rating system we no longer use. To know what stamp to select, obtain the exact weight of the window sash. Then see if that weight falls into one of the weight ranges we list alongside each stamp option under the balance product description.
