The mounting brackets are vertically fastenable to a telecommunications equipment rack using the existing rack dress screws and mounting holes distributed along the side rails of the telecommunications equipment rack. The mounting brackets further include a plurality of cable management fingers and hinge apertures. The hinge apertures of the mounting brackets are designed to accept a plurality of hinge posts located along a first side of the door, thusly allowing the door to be pivotably moveable relative to the mounting bracket.
