A cable duct coupler for coupling a first cable duct section to a second cable duct section without the need for tools, the cable duct coupler comprising a channel portion, a first outer guide element and a second outer guide element, a barb mount extending from at least one of the channel portion and the outer guide elements, and a barb having a body and first and second arms extending from the body, the barb being mounted on the barb mount, wherein at least a portion of the first arm extends at an angle between the first portion of the channel portion and the barb body and at least a portion of the second arm extends at an angle between the second portion of the channel portion and the barb body.

Cable duct coupler

A hinged duct system with a hinged cover is provided that includes a base member and a duct cover. The base member has a bottom wall and sidewalls defining a receiving channel. A distal end of at least one of the sidewalls includes a base hook having an inwardly directed flange portion and a convex portion extending outwardly from the receiving channel towards the at least one sidewall. A distal end of the convex portion is spaced from the flange portion to define a cavity therebetween. The duct cover is hingedly attached to the at least one sidewall. The duct cover includes at least one curved end portion forming a hinge end section. The hinge end section includes a cover hook having a distal end receivable in the base member cavity and a cover flange spaced inwardly from the cover hook. When the duct cover is mounted to the base member the cover flange abuts the convex portion of the base hook with a pre-load pressure that creates a point of contact pressure engagement point on the convex portion. The duct cover is pivotal about the hinge end section between open and closed positions and the cover flange maintains a substantially continuous point of contact force against the convex portion sufficient to retain the duct cover in any of various positions between the open and closed positions. A double hinged cover can also be provided.
