I need 2 balances for an aluminum window , and 4 takeout clips. probably Milgard. 20 years old. 27-5/8" long (measuring just the steel), 1/2"wide, looks like series 385, wings at each end.
the stamp is 27-4-BS (possibly BSI) ,pa.
The takeout clips are for an aluminum frame and break easily when removed. replacement clips appear to be for a thicker, vinyl frame.
