ABSTRACT:
A universal application unequal flange telephone equipment rack is provided to obviate the need for open and closed duct network bays and open and closed duct unequal flange equipment racks. The universal rack is constructed of a pair of upright frame members which are joined by a first pair of horizontal frame members at the top thereof and a second pair of horizontal frame members at the bottom thereof. The upstanding frame members are formed from identical metal channels having a U-shaped cross-section comprising a web with one relatively short side portion and another relatively long side portion wherein the web and side portions of each upright frame member are directed outwardly relative to the other frame member. Each pair of horizontal frame members is formed from identical C-shaped metal channels which are spaced apart so as to define a slot therebetween. The symmetrical construction of the equipment rack allows for different applications including use as either a front or rear access rack merely by inverting the rack.
