A portable unwinder for electrical cable and the like comprising in combination:
- a base;
- a stud centrally located upon and extending upwards from the base;
- a thrust bearing about the stud and resting upon the base;
- a rotatable disc resting upon the thrust bearing and approximately centered relative to the stud;
- and
- means assembled to and projecting upwards from the base for supporting and retarding the rotation of the disc, the combination permitting rotation of the disc relative to the base and usable as an unwinder by placing coiled material upon the disc and pulling a loose end of the material, whereupon the disc and the coil upon it rotate in response to the pulling force.
