ABSTRACT:
A building entrance box providing an interface between a signal transmission media cable having a first plurality of filamentary signal transmission elements and a second plurality of individual filamentary signal transmission elements. In a first embodiment, moisture infiltration is reduced by providing potting material in a transition region between a splice chamber of the box and a connector chamber of the box. In another embodiment, a plastic protector panel is specifically shaped to reduce condensation and to reduce the effects of any condensation. Modular protector panels mounted in the box are automatically grounded when mounted to a conductive chassis plate and are so arranged that input and output wires are isolated from each other. Mounting of stacked boxes in a predetermined alignment is effected by a first embodiment of a bracket assembly having a variable overall length but a fixed horizontal alignment, and by a second embodiment of a bracket which is breakable by an installer to achieve a desired bracket length.
