Claim 1
Independent Claim
219 words
A hollow, octagon-shaped floor box comprising: a bottom, four long sides and four short sides each extending up from the bottom to form the hollow box, each two adjacent long sideS extending perpendicular to each other with a short side extending therebetween and oriented at an obtuse angle to each long side; each short side comprising first and second sections, the first section being an extension of one of the long sides and the second section being an extension of the other long side, also the first and second sections each being L-shaped and the edge of the leg of the first section abutting the edge of the foot of the second section and the edge of the foot of the first section abutting the edge of the leg of the second section; a leveling lug extending outwardly from the top of said foot; a fastening lug on the top of the first section and extending outwardly therefrom and overlapping the second section and being spot welded thereto; a mounting lug at the top edge of said other long side and extending in to the box and generally perpendicular to the long side; and said bottom, said sides, said leveling, fastening and mounting lugs all being integral and made from pregalvanized metal and formed on a multi-stage progressive die.
