An enclosure includes a housing longitudinally extending from an open first end to a closed second end. The housing defines an internal cavity extending in the longitudinal direction, the internal cavity having a circumference in a direction transverse to the longitudinal direction. A base member is configured for separable attachment to the open first end of the housing to provide an enclosed configuration. A support frame is secured to the base member and extends longitudinally within the internal cavity of the housing in the enclosed configuration. The support frame includes at least one portion that provides support about substantially the entire circumference of the internal cavity at a location between the first end and the second end of the housing.
