ABSTRACT:
A spool suitable for winding material thereon includes an axially extending body having a proximal end and a distal end joined by an outer surface. A cam is rotatably mounted adjacent to the body for rotatable movement between a closed position and an open position. In the closed position, the cam secures the material to the spool and a portion of the cam extends radially outwardly from the body to define a first effective diameter of the spool. In the open position, the cam is spaced from the body to release the material secured to the spool and the portion of the cam retracts toward the body to define a second effective diameter of the spool which is less than the first effective diameter.
