An enclosure includes a housing and a sealing unit that mounts within a sealing unit opening of the housing. The sealing unit provides a peripheral seal between the housing and the sealing unit and provides seals around cable ports. The sealing unit can be mounted to and removed from the housing through the sealing unit opening. The base lacks a permanent retention structure at the outer end of the base for retaining the sealing unit in the base. A cover is removable from the base without requiring the sealant arrangement to be depressurized.A fastening arrangement releasably retains the sealing unit in the sealing unit opening. |
