Abstract

Fiber optic equipment guides and rails and related methods are disclosed. In one embodiment, the fiber optic equipment guides and rails have at least one stopping member disposed therein to provide at least one stopping position during movement. The fiber optic equipment guides and rails can be included in fiber optic equipment to support movement or translation of the fiber optic equipment for access. Such fiber optic equipment can include, but is not limited to, fiber optic equipment chassis, drawers, equipment trays, and fiber optic modules. The fiber optic equipment guides and/or rails include at least one stopping member configured to provide at least one stopping position during movement. Stopping positions allow fiber optic equipment to be retained in a given position during access to the fiber optic equipment. The stopping positions are configured to be overcome with additional force to allow further movement of the fiber optic equipment.
