Patent ID: 8177157

Claim:
A spool for retaining wire, comprising: a contiguously cylindrical barrel having an inner surface defining an inner diameter, an outer face for receiving associated wire, a pair of opposed ends, wherein both ends of the barrel have a plurality of laterally-extending tabs extending therefrom, each of the plurality of tabs having a width, a flange penetration length perpendicular to the width, and a thickness; a pair of opposed flanges having a uniform diameter and an inner face and an outer face, wherein the inner faces of each of the flanges includes an interrupted annular groove comprising a plurality of slots, sized to receive the laterally-extending tabs from the ends of the barrel, the interrupted annular groove comprising a plurality of slots separated by spaces therebetween, each slot having a depth, said flange penetration length being less than or equal to said slot depth, said plurality of tabs and slots determined by a size of said spool and a diameter of said wire and spaced so that if said flanges are forced apart from said barrel, said wire cannot be forced into said slots in said interrupted annular groove; and one or more bolts operatively connected to secure each flange to the opposed ends of the barrel.
