An electrical box includes a body, a cover that is movable relative to the body, and an electrical connection point that is mounted to the cover. The electrical connection point may be one or more of an electrical receptacle, a data jack, and/or the like. The cover may be attached to the body by a sliding hinge connection or a sliding pin connection that allows the cover to rotate relative to the body as well as translate relative to the body. An air pocket substantially filling a compartment in the cover is maintained during an opening or closing of the electrical box.
