A yarn package holder for accommodating yarn package tubes and cones of various sizes, wherein a fixed, cantilevered contact arm is provided with a separate layer of friction material providing a friction surface and has one end of a first spring member pivotally connected to the distal end thereof, and one end of a second spring member fixedly connected to the other end thereof. The friction surface engages the inner wall surface of the tube or cone on one side thereof and the free end of the first spring member engages the inner wall surface of the tube or cone on the opposite side thereof, and the free end of the second spring member engages the first spring member intermediate the ends thereof to provide a displaceable fulcrum therewith. An equal biasing force is applied to the inside surface of the tubes or cones no matter what their size might be.
