These balances are for a small bathroom window that is single-hung.
They measure 10 inches, including the top and bottom plastic guides.
They have a "clip" on the end of the string that attaches to the stationary window frame - one of the balances is missing its clip in these photos.
They are stamped "08 3 PV" and also "B.S.I." The channel length is 8-5/8" and the width is 1/2".
I need a pair of these, please.
