ABSTRACT:
A suspended ceiling system having main runners and/or members extending parallel with the cross members spaced therealong to form rectangular sections, the cross members being provided with tongues extending from the end and received in an aperture or slot in the web of the main member with the tongue being provided with spaced abutment surfaces separated by an elongated aperture extending parallel to a bead of the cross member and the tongue having abutment surfaces and flaps for coacting with the tongue from the opposite direction to form an end-to-end connection between the cross members. The elongated aperture besides spacing the two abutment surfaces that engage the web of the main member to hold the cross member in place provides an aperture on each side of the web of the main member for receiving a clip such as a seismic clip to positively lock the members together.
