Claim 8

A cap member for T-beams of suspended ceiling construction comprising: a longitudinal hollow member having two opposed major walls and two opposed minor walls connecting the major walls, one of the major walls having a lengthwise opening communicating with the interior thereof through which the flange portion of a T-beam can be inserted internally of the hollow member, the major wall with the opening having a width greater than the flange portions of the T-beams; and a pair of spaced-apart projections within the hollow member jutting from the inside surface of the major wall having the opening towards the other major wall, the projections running parallel to each other on opposite sides of the opening, one of the projections having a shorter height dimension than the other, the hollow member having dimensions locating one of the minor walls spaced from and laterally outwardly of the shorter projection, the height of the shorter projection with respect to the other major wall and the location of the minor wall laterally outwardly of the shorter projection permitting flange movement of the T-beam laterally outwardly of the shorter projection through the space between the shorter projection and the other major wall, the width of the opening being less than the combined flange width of the flange portions of the T-beam.

Claim 9

A cap member for T-beams of suspended ceiling construction comprising: a longitudinal hollow member having two opposed major walls and two opposed minor walls connecting the major walls, one of the major walls having a lengthwise opening communicating with the interior thereof through which the flange portion of a T-beam can be inserted internally of the hollow member, the major wall with the opening having a width greater than the flange portions of the T-beams; and a pair of spaced-apart projections within the hollow member jutting from the inside surface of the major wall having the opening towards the other major wall, the projections running parallel to each other on opposite sides of the opening, one of the projections having a shorter height dimension than the other, the hollow member having dimensions locating one of the minor walls spaced from and laterally outwardly of the shorter projection, the height of the shorter projection with respect to the other major wall and the location of the minor wall laterally outwardly of the shorter projection permitting flange movement of the T-beam laterally outwardly of the shorter projection through the space between the shorter projection and the other major wall, the width of the opening being less than the combined flange width of the flange portions of the T-beam.

Claim 10

A cap member recited in claim 5 where the other major wall is multiplaner.

Claim 11

A cap member for T-beam members of suspended ceiling construction comprising: a longitudinal hollow member having two opposed major walls and two opposed minor walls connecting the major walls, one of the major walls having a lengthwise opening communicating with the interior thereof through which the flange portions of a T-beam can be inserted internally of the hollow member, the major wall with the opening having a width greater than the flange portions of the T-beam; and a pair of spaced-apart projections within the hollow member jutting from the inside surface of the major wall having the opening toward the other majOr wall, the projections running parallel to each other to opposite sides of the opening, the minor walls located laterally outwardly in spaced relation from the projections, one of the projections having a shorter height dimension than the other, the height of the shorter projection with respect to the other major wall permitting flange movement of the T-beam laterally into the space between the projection and its associated minor wall, the other projection having a height with respect to the other major wall that precludes entry of T-beam into the space between the other projection and its associated minor wall, the width of the opening being less than the combined flange width of the flange portions of the T-beam.
