Claim:
1. An enclosure comprising: a housing having an end defining a sealing unit opening; a sealing unit that fits within the sealing unit opening, the sealing unit including a sealant arrangement that defines a plurality of cable ports that extend through the sealant arrangement in an axial orientation, the sealing unit also including an actuation arrangement that pressurizes the sealant arrangement within the sealing unit opening, the actuation arrangement including inner and outer pressurization structures between which the sealant arrangement is axially positioned, the sealant arrangement being pressurized under spring pressure between the inner and outer pressurization structures when the actuation arrangement is actuated, the sealant arrangement providing a peripheral seal between the housing and the sealing unit when the sealing unit is positioned within the sealing unit opening and the sealant arrangement is pressurized by the actuation arrangement, the sealant arrangement including a plurality of cable sealing modules each sized to form only a portion of the sealant arrangement, the cable sealing modules being individually installable between the inner and outer pressurization structures and being individually removable from between the inner and outer pressurization structures, the cable sealing modules each defining at least one of the cable ports, the cable sealing modules including volumes of sealant at least partially axially contained between first and second axial containment structures, the volumes of sealant of the cable sealing modules including cable sealing surfaces that extend around the cable ports so as to define the cable ports, the volumes of sealant of the cable sealing modules also including exposed outer sealing surfaces that surround peripheries of the sealing modules; wherein the sealant arrangement includes at least three of the cable sealing modules; wherein portions of the exposed outer sealing surfaces of the cable sealing modules form at least a portion of the peripheral seal between the housing and the sealing unit; and wherein the sealing modules are formed by bodies having wrap-around configurations for allowing cables to be laterally inserted into the cable ports.
