I need to replace two BSI channel balances for my window, along with the plastic hardware that screws into the top of the window pane.
The channel balance is stamped with "31 C". The metal frame measures nearly exactly 32 inches (photo included).
Unsure of the name of the plastic tab that screws into the top of the window to retain the channel balance, but it has broken off and also needs replaced (picture of broken tab included).
Thanks in advance!
Eric
