Plugs and covers for a utility enclosure or penetration prevent the ingress of concrete. One plug includes a sidewall configured to be received in an open end of the utility enclosure or penetration, the sidewall defines a periphery. The plug also includes a lid extending over one end of the sidewall, the lid having a body extending over an inner peripheral area defined by the sidewall, and a flange extending outwardly from the body. A cover fits over a top of the enclosure and seals to the enclosure or a blank covering the enclosure. Connector plugs prevent concrete from entering connector openings and an environmental sealing material is applied to an outside of the enclosure. A clip for securing the utility enclosure to a form is also disclosed.

A link box includes a housing that defines an enclosure, an electrical connector within the enclosure, an aperture formed through a wall of the housing, and a cable entry seal secured to the housing at the aperture. The cable entry seal receives a cable inserted into the housing for connection to the electrical connector. The cable entry seal includes first and second parts that are removably secured together. The first part includes a flange and an externally-threaded portion that extends outwardly from the flange. The externally-threaded portion is inserted through the aperture from within the enclosure such that the flange abuts an internal surface of the wall. The second part includes an internally-threaded body and a seal conduit that extends outwardly from the internally-threaded body. The internally-threaded body is threadingly engaged with the externally-threaded portion of the first part and the seal conduit surrounds and seals the cable.
