Wire Ferrule Assortments

Install, extend, or rewire a circuit without hunting down new wire ferrules. These assortments include ferrules for most small and medium wire gauges.

Ferrules turn flexible, stranded wires into one rigid, straight wire that slides into spring-clamp and lever-clamp terminal blocks. When attaching your wire, use a wire ferrule crimping tool to avoid a damaged barrel and loose connection.

Nylon Insulation—In addition to preventing short circuits, this wear-resistant insulation protects wire from vibration and rubbing against nearby edges.

Polypropylene Insulation—Plastic covers the metal barrel to protect the wire from cuts, contamination, and short circuits. The choice for damp environments, polypropylene keeps its shape and strength better than nylon when exposed to moisture.

Noninsulated—The basic, economical option when short circuits from nearby wiring aren't a concern.
