1. A system comprising:

  • an elongated rotatable member for receiving elongated flexible material wound around the elongated rotatable member and for dispensing the elongated flexible material therefrom by rotating, wherein the elongated rotatable member includes a first tube and a second tube, and wherein the second tube is shorter lengthwise than the first tube, is located around the first tube, and is centered along a length of the first tube;

    a first primary collar located around the first tube proximate to a first lengthwise opposing end of the elongated rotatable member and pressed against a first edge of the second tube;

    a second primary collar around the first tube proximate to a second lengthwise opposing end of the elongated rotatable member and pressed against a second edge of the second tube, wherein the first primary collar and the second primary collar define a lengthwise center of the elongated rotatable member onto which the elongated flexible material is wound, and wherein the first primary collar and the second primary collar resist outward pressure thereon from the elongated flexible material;

    a first retention collar secured with friction around the first tube proximate to the first lengthwise opposing end of the elongated rotatable member to secure, with friction, the first primary collar in place against the first edge of the second tube for resisting the outward pressure thereon from the elongated flexible material and to prevent the first primary collar from shifting lengthwise along the elongated rotatable member towards the first lengthwise opposing end of the elongated rotatable member; and

    a second retention collar secured with friction around the first tube proximate to the second lengthwise opposing end of the elongated rotatable member to secure, with friction, the second primary collar in place against the second edge of the second tube for resisting the outward pressure thereon from the elongated flexible material and to prevent the second primary collar from shifting lengthwise along the elongated rotatable member towards the second lengthwise opposing end of the elongated rotatable member.
