Total Claims: 7
Claim 1
Independent Claim
177 words
An electric fixture hanging device for hanging an electric fixture from a suspended ceiling supported by an overhead structure, said electric fixture hanging device comprising: a box having a closed top, an open bottom, and a continuous side wall having a first height; said side wall having four slots formed therein at 90 degree intervals for engagement with the suspended ceiling and said slots extending inwardly from said open bottom such that said slots extend inwardly from said open bottom by a second height that is less than said first height and wherein said slots have closed upper portions extending upwardly toward said box top, with breakable tongues removably attached to said upper portions of said slots for varying said slot height; and fixture fasteners for connecting the electric fixture to said box, wherein said fixture fasteners extend from said box top in the direction of said box bottom and are of sufficiently greater length than said first height such that distal ends of said fixture fasteners form connecting means for connecting the fixture to said box.
