The invention pertains to a mechanical device useful for distributing, routing, and managing fibers, such as optical fibers. The device is particularly useful applications such as computers and telecommunication equipment. In one embodiment, the inventive device comprising conductors and a flexible substrate. The flexible substrate has (a) a central body having at least one input end where the conductors enter; (b) a plurality of primary tabs extending from the central body, each tab having at least one means for retaining the conductors; and (c) a passageway formed from folding the device along a plurality of folding slots such that a plurality of locking features mate with a plurality of interlocking slots and the primary tabs, the conductors disposed inside at least a portion of the passageway. The device manages, routes, and distributes conductors without the use of an adhesive.
