A device is provided for dispensing a length of elongate material wound on the barrel of a spool. A support is provided for the spool including first and second end plates. The end plates are positioned in a spaced relationship. A support hub extends from each plate and is engaged within an opening in the spool on opposite sides thereof, such that the spool may rotate about the support hub. The support hub includes a peripheral dimension that permits a dynamic, pivoting motion of the spool about the contact with the hub. The support hub normally positions the spool in a radially offset position and engages a friction member formed adjacent the periphery of the flange of the spool. During unwinding, pulling of the end of the elongate material causes the spool to pivot in the direction of the pulling force and away from the friction member. Once the pulling force is removed, the spool pivots about the hub, back into frictional engagement with the friction member.
