Made from a flexible PVC, supplied coiled but uncoils to lay flat. Protects cables, reduces the risk of split insulation and damaged conductor strands. The danger of electrocution and heat spots (that create fire risks), is also minimised. Connector pins provide an effective friction-fit connection that can be pushed-in, then later pulled apart, in adjoining lengths to cover whatever length of cable is required. Supplied with 2 connector pins.
