Cables run through almost every building. It's important that they don't run wild, which is why clear cable labelling is essential for both electricians and workers. The extremely fine tip ensures that the edding 8407 cable marker can mark cables in the appropriate way. Whether the cables run indoors or outdoors, the permanent, waterproof and light-resistant marker marks them all perfectly. And because good cabling also needs good colour coding, this special edding is available in a set of four different colours. The cap can be slipped onto the end of the barrel so it can't get lost. High quality brand product.
