Closure with axial pull protection for connectorized cables

A telecommunications closure comprising:

• a base holding an optical adapter and defining an access opening, the optical adapter defining opposite first and second ports;
• a cover that cooperates with the base to define an interior having a height, a width, and a depth that are transverse to each other, the cover being movable relative to the base between an open position and a closed position, the cover blocking access to the optical adapter through the access opening when in the closed position, the cover allowing access to the optical adapter through the access opening when in the open position, the cover having an inner surface and an opposite outer surface, the inner surface of the cover facing the base and the outer surface of the cover facing away from the base when the cover is disposed in the closed position, the cover and the base also cooperating to define a cable port that is aligned with the first port of the optical adapter;
• and
• a support member carried by the inner surface of the cover to move with the cover between the open and closed positions, the support member being offset from the first port of the optical adapter along the height of the interior and partially overlapping the first port of the optical adapter along the width of the interior.
