I'm putting together an order for parts for some windows in a 1994 era townhouse; the 29" blue tip
series 600 balances and the 17/32 pivots match up to what I have, but my tilt sash latches are 2.5" C to C, with 5/8 from the outer screw to the sash edges. Your
26-215 latch says 2.5" C to C, but 3/4" outer screw C to sash edge. OK choice? Don't know the window brand, it has an internal grid between the two panes.
