Abstract
A cable duct coupler includes an inner wall shaped to define a cable-receiving channel therebetween, a support rib extending from the inner wall and including at least one mount clip, an axially extending outer wall outwardly spaced from the inner wall to define a duct section receiving space therebetween, and at least one removable retention clip. The retention clip has arms that extend into the duct section receiving space, such that upon insertion of cable duct sections, such as a cable trough or fitting, into the duct section receiving space, the retention clip biases the duct sections against the inner wall to retain the duct sections together. The removable retention clip is movable between an insert position in which the arms extend into the duct section receiving space to allow coupling and a detach position in which the arms no longer extend into the duct section receiving space to allow disassembly of the discrete duct sections. The retention clip is formed of a resilient material such as metal and may be bent to form arms that are angled towards the support rib of the duct coupler. The arms may be sharpened or serrated at an edge thereof to increase retention of the duct…
