PVC Conduit. These conduits are made out of PVC Material. Grey, Flexible Plastic Spiral Conduit
Some early electric lighting installations made use of existing gas pipe serving gas light fixtures which had been converted to electric lamps. Since this technique provided very good mechanical protection for interior wiring, it was extended to all types of interior wiring and by the early 20th century purpose built couplings and fittings were manufactured for electrical use.
