A shield and method for inhibiting electromagnetic interference (EMI) emissions from an enclosure is disclosed. The shield includes a cover portion and a plurality of extensions adjacent the cover portion, the extensions together at least partially defining a channel extending along at least a portion of the cover portion, the channel having substantially parallel boundaries, the channel being configured to received a portion of the enclosure and to slidably engage the enclosure such that, when engaged, the cover portion inhibits electromagnetic interference emissions from the enclosure. The method includes aligning a plurality of extensions of a shield with a portion of the enclosure and sliding the extensions into engagement with the portion of the enclosure until the shield covers an opening in the enclosure, thereby inhibiting electromagnetic interference emissions from the enclosure through the opening.
