Fiber optic enclosures employing clamping assemblies for strain relief cables and related assemblies and methods are disclosed. The fiber optic enclosures may be part of a fiber optic terminal in a fiber optic network. The fiber optic enclosures may include openings in the walls of the fiber optic enclosure. A cable fitting assembly may be attached to a portion of the wall around an opening to form a passageway for fiber optic cables to enter the fiber optic enclosure. An elongated member may be used to guide the fiber optic cables through the passageway. The elongated member may have a first end and second end. The elongated member may include a clamping assembly at the first end to provide strain relief to the fiber optic cables by clamping strength members of the fiber optic cables.
