Channel Balance replacement identification

I have a single hung window that requires channel balances to be replaced.
I have identified as follows:
1-length 28"
2-width 9/16"
3-depth 1-3/32"
4-ID stamped '2730'

I am unsure of which item identification to request for replacement.

I have additional photos which can be uploaded if necessary.

Hello,

Take a look at our S390-28 channel balance with a 2730 strength option. The bottom attachment would measure 1-1/8" deep. Just something to double-check. Thanks for posting!
