System for mounting a plurality of fiber optic cassettes to a high density cassette shelf

A system for mounting a plurality of fiber optic cassettes, the system comprising:

• an enclosure dimensioned to contain the plurality of fiber optic cassettes in a horizontal array;
• first and second angle-iron-shaped elongated members affixed within the enclosure, each of the first and second elongated members comprising a first elongated section having a generally flat first mounting surface with an array of shelf fastener perforations disposed at regular intervals along the first mounting surface, each shelf fastener perforation being dimensioned to receive a cassette fastener for affixing a fiber optic cassette against the first mounting surface, and a second elongated section that is perpendicular to the first elongated section, wherein the first and second elongated members are arranged so that fiber optic cassettes may be secured to the first and second elongated members, using corresponding shelf fastener perforations;
• and
• a plurality of adapter brackets, wherein each of the adapter brackets comprises:
• first and second generally planar sections spaced apart from one another;
• a third section joining the first and second sections at one end of each of the first and second sections, the third section comprising a bracket fastener perforation dimensioned to receive a cassette fastener for affixing a fiber optic cassette against a first generally flat mounting surface of the third section;
• first, second and third stabilization features and a locking feature, the first and second stabilization features protruding from the first planar section, the third stabilization feature and the locking feature protruding from the second planar section, wherein the first second and third stabilization features and the locking feature are collectively arranged to secure the adapter bracket to one of the first and second elongated members and to simultaneously allow the adapter bracket to move in a horizontal direction with respect to the first elongated section without resistance,
• wherein the first and second stabilization features are spaced apart on the first planar section by a distance that corresponds to a height of the second elongated section, and wherein the third stabilization feature and the locking feature are spaced apart on the second planar section by a distance that corresponds to a thickness of the first elongated section.
