Cable drum for electrical or telephone cables

摘要

The drum has a drum part (FU) with two outer holder discs (J,S) which have a larger diameter than a central cable and are used to hold the central cable in place. One of the outer holder discs has a slot in it with markings. As the cable is wound around the diameter of the drum part, the cable can be viewed and related to the markings to determine the length of cable left in the reel.
