Claim 7
Dependent Claim 59 words
An assembly in accordance with claim 4 wherein said tapping finger portions extend diametrically in opposite directions from said plug assembly and terminate in free portions adapted to contact said conductors, the spacing of said free portions of said fingers being greater than the transverse dimension of said access cutouts but smaller than the longitudinal dimension of said cutouts.
Claim 8
Dependent Claim 53 words
An assembly in accordance with claim 5 wherein said channel includes a longitudinally extending locking groove and said second plug member includes a locking finger vertically offset from said tapping fingers, said locking finger being dimensioned to be received snugly in said locking groove in said rotated position of said second plug assembly.
Claim 9
Dependent Claim 103 words
An assembly in accordance with claim 4 wherein said channel includes at one side a laterally offset ceiling tile support flange adapted to provide vertical support for ceiling tiles adjacent said side, the assembly including a tile support clip including a vertically directed web arranged to lie adjacent the opposite side of said channel, said web including spaced support tabs overlying the uppermost edge of said channel adjacent said opposite side to support said clip, said web including at the lower edge an outwardly directed tile support shoulder adapted to engage and vertically support tiles disposed adjacent said opposite side of said channel.
Claim 10
Dependent Claim 24 words
An assembly in accordance with claim 7 wherein the spaces defined between said support tabs register with said access cutouts in said bridging member.
Claim 11
Dependent Claim 126 words
