An enclosure includes a housing defining an internal splicing area and at least one port at least one port configured for passage of at least one telecommunications cable into the enclosure. The enclosure protects the optical fibers, optical fiber splices and optical devices contained therein. A support basket is disposed in the splicing area and extends longitudinally within the housing. The support basket is shaped to substantially conform to a portion of the circumferential shape of the splicing area. A repositionable, removable support platform is disposed on the support basket in a first orientation for storage and disposed in a second orientation for installation and maintenance of the fiber optic splices and optical devices housed in the enclosure. The optical fiber splices and optical devices are disposed in a splice tray which is adjacent to the support platform. Additionally, the support basket includes a multilayer slack storage compartment.
