Wire end ferrules are also commonly known as boot lace ferrules or cable end sleeves. They are used to contain strands of wire to ease entry in to screw clamp conections such as terminal blocks. Wire end ferrules are available in insulated, twin insulated and un-insulated formats. Insulated ferrules follow either the French, German or DIN colour codes. We focus here on the extensive Klauke range but we can also offer Cembre ferrules.
