Abstract
A one-piece reclosable ducting system for electrical wiring or the like. The duct system includes an elongated channel and a mating channel cover. The channel and channel cover are formed as integral members in a dual-durometer plastics co-extrusion process. More specifically, the channel and channel cover are maintained in operative relationship along respective first edges by a flexible plastic hinge, again, co-extruded with the channel and cover. The flexible plastic hinge permits repeated access and closure of the channel without hinge fatigue. A cantilever tension arm or support beam is integrally formed in the ducting system and extends from the channel to bias and retain the channel cover in proper orientation thereby assuring latching of the cover while simultaneously maintaining overall ducting system structural integrity.
