ABSTRACT:
A collapsible spool for storing, winding, unwinding and transporting cable products and the like is provided. The collapsible spool includes a pair of opposing side panels having a plurality of foldable arms extending therebetween. The foldable arms include a first segment and a second segment pivotally joined at adjacent ends for allowing the arms to fold radially outward for collapsing the spool. Each arm is hingedly connected at each end to the opposing side panels. In particular, each arm can include an inner hinge arrangement located at one end and an outer hinge arrangement located at an opposite end. The inner hinge and outer hinge prevent the arms from folding radially inward. Further, the inner hinge and outer hinge fold together when the spool is collapsed.
