We need channel balances for our windows.
These window panes are 36"x36" All of our windows in house are same size.
The balance channel measures 28" (metal channel only)
It is stamped with "27C"
The bottom is non-tabbed.
The bottom part does measure 1-1/8"
I think this is a Series 390 but would like confirmation.
