A sealing assembly for sealing a corner of an enclosure is disclosed. The sealing assembly includes a substantially rigid bracket and a flexible seal. The bracket includes a first latch and a second latch. The first and second latches are configured for releasable connection to an enclosure adjacent a corner with the first and second latches on opposing sides of said corner. The bracket is configured to provide a force to couple the flexible seal to a corner of an enclosure when the bracket is attached to said enclosure. The flexible seal includes a first surface for coupling to the corner of the enclosure, and a second surface opposite the first surface. At least a portion of the second surface is configured for contact with the bracket. The flexible seal may include a connector for releasable connection to the bracket.
