A cable dispensing system for unwinding a spool of cable not having a central core, the system comprising a tub having a base and a side wall with a side wall opening partially forming an inner space sized to fit the spool, the system further including an inner assembly having a base plate and a bearing assembly between the plate and the tub base, the bearing assembly supporting both the axial load and providing free rotation of the plate relative to the tub base about an inner space axis and unrestricted rotation of the associated spool about the system axis, the opening in the side wall allowing passage of the associated cable out of the inner space wherein pulling the cable out of the inner space rotates the associated spool about the inner space axis and unwinds the cable from the spool with low resistance and without kinking.

The cable dispensing system of claim 1, wherein the rolling members of the bearing are a plurality of rolling members spaced about the system axis by a bearing spacing and the bearing spacing being at least three inches from the central axis. 3. The cable dispensing system of claim 1, wherein the rolling members are a plurality of ball bearings. 4. The cable dispensing system of claim 1, wherein the bearing assembly is an annularly shaped bearing having a first bearing plate fixed relative to the base plate and a second bearing plate fixed relative to the tub base with a plurality of rolling members between the first and second bearing plates and guided by the first and second bearing plates, the roller members being spaced about the system axis by a bearing spacing and the bearing spacing being at least three inches from the central axis. 5. The cable dispensing system of claim 4, wherein the rolling members are centered under the associated annular spool body of the associated coiled spool of cable. 6. The cable dispensing system of claim 4, wherein the first and second bearing plates are secured relative to one another to retain the bearing assembly with the tub. 7. The cable dispensing system of claim 1, wherein the rolling members of the bearing assembly engage at least one of the base plate bottom side and the tub base inner surface. 8. The cable dispensing system of claim 1, wherein the side wall cable opening is an elongated opening having a side wall cable opening width parallel to the tub base and a side wall cable opening height extending between the tub bottom and the upper side wall edge, the side wall cable opening width being greater than the side wall cable opening height. 9. The cable dispensing system of claim 8, wherein the side wall cable opening has a rounded edge that has an edge thickness greater than a thickness of the at least one side wall of the tub. 10.
