A structural connection arrangement and method for connecting at least two sash, stile, mullion, or frame members of window and/or door frame assemblies that are oriented in crossing orientations when connected to one another. The connection arrangement includes at least two elongate members that each extend along a respective longitudinal axis. A pair of openings are formed in one of the elongate members and oriented to face in a crossing direction relative to the longitudinal axis of the respective member. A pair of connection members is secured to the other of the elongate members of the frame assembly and extends beyond the elongate member so that each connection member cooperates with one of the pair of openings and overlaps an interface between the two elongate members.
