Abstract

A one piece T section used interchangeably as both a main T member and a cross T member in a supporting grid system for suspended ceilings. The interchangeable T sections have locking connectors engageable to interlock a pair of sections in end to end relation to form a main T splice with their tile supporting flanges substantially abutting. When the sections are used as cross T members, the locking connectors engage the web of a section used as a main T member and the flanges of the cross T sections overlie the flanges of the main T section with which they are interlocked.
