ABSTRACT:
A universal flexible transition connector for connecting the ends of spaced apart wiring ducts is described. The connectors are flexible along six axes of change to provide a single fitting capable of making any number of gradually curved interconnections between ducts required for use in fiber optics installations. The connectors include a duct transition converter having a cuff formation in one end for gripping attachment to the multi-sided end of a first wiring duct. The opposite end of the converter includes a resilient sleeve portion for cooperatively engaging the end of a flexible tubing member. A similar converter provided on the opposite end of the flexible tubing may be connected to the second duct end to form a smooth transition connection between duct system elements of a premises wiring system.
