ABSTRACT:
A suspended ceiling grid system formed of main runners (10) and cross runners (40) disposed at right angles to the main runners to define grid openings for the reception of ceiling tiles (T). Each of the runners (10, 40) includes a bulb (12, 42) a pair of webs (14, 44) depending from the bulb to define a recess therebetween, and a pair of tile supporting flanges (16, 46) extending in opposite directions from the lower edges of the webs. The tiles (T) when assembled onto the flanges (16, 46) of the main and cross runners (10, 40) resiliently displace the webs (14, 44) from their normal unstressed positions to cause the webs to center the tile. Simulation means (76) is carried by the runners in underlying relationship at the intersection of the main and cross runners (10, 40) to simulate a continuous recess at the intersection.
