ABSTRACT:
A support runner for use in suspended ceiling grid systems is disclosed with the support runner being useful in ceiling systems having an exposed flange for decorative purposes. The support runner comprises: a lower decorative trim member; an upper inverted T-runner; and, an intermediate spline member. The decorative trim member has a decorative lower surface and an engageable upper surface. A spline member is engaged about the engageable upper surface of the decorative trim and extends substantially along the full length of the decorative trim. The upper surface of the spline is an engageable slot. An inverted T-runner is supportingly engaged to the engageable upper surface slot of the spline and extends along the spline a distance sufficiently less than the length of spline and trim members to accommodate heat expansion distortion of the inverted T-runner. When the ceiling system is exposed to heat, the inverted T-runner continues to hold the ceiling panels even though the spline loses structural integrity and disengages the decorative trim.
