摘要： A new and useful barrier device for a utility system cover is provided. The barrier device is designed to be coupled to a utility system cover (e.g. a water meter cover), in a way that effectively seals the opening in the cover against ingress of dirt, debris, animals, etc. Moreover, the barrier device also provides a structure that enables a hook like tool to engage and manipulate the coupled barrier device and cover, while maintaining the barrier against ingress of dirt, debris, animals, etc. The barrier device includes a hood with a border that at least partially flattens against a utility system cover as the baffler device is coupled to the utility system cover, so that the border of the hood and the utility system cover combine to form a baffler to materials and objects near the border of the hood. A stem extends from the hood, and is pressed into the utility system cover, in a way that effectively couples the baffler device with the cover. For covers that are too thick for the one piece cap structure, extender structure is provided, to extend the thickness of the cover(s) to which the barrier structure can be coupled.
