Abstract
Entrance terminal housing having walls sealed together at their junctions and defining a chamber opening. A removable cover is provided for the opening and a seal between walls and cover. In preferred arrangements, removable covers isolate terminals within the housing from other terminals and also isolate the terminals from the rest of the chamber. A fire resistant conductor sleeve is provided of flexible material and is of radially expansible and collapsible tapered tubular form for sealing around a range of numbers of conductors passing through a wall of the housing. In one construction, the sleeve has axially extending corrugations which allow for its expansion and collapse.
