Abstract: A connection box for communications cabling, especially useful for fiber optic connections, which is capable of being mounted entirely within a standard depth wall or column framing. The box has a depth which is less than the depth of a standard office wall, open to the outside, and with an open bottom (as the box is mounted vertically in the wall). Cables enter the box, either through the open bottom or through a cable fitting, and are attached to a fitting on a removable connector module mounted to the box. A cover can be attached over the open side of the box, flush with the wall, concealing the interconnections.
