I am looking to replace two channel balances for the same window. They are 22in in length and 1/2in wide. They have been stamped with 2120 and the letters B.S.I. It looks as though a tab is broken off of the plastic piece at the end of each one.
I am also missing the latch at the top of one of my window channels. I have included a picture of the remaining one.
Could you help me in identifying the correct parts to replace. Thanks!
Gary
