A plastic cover on the barrel provides electrical insulation to prevent short-circuiting with nearby wire. These wire ferrules add strength and stability to stranded wire to protect it from damage and speed insertion into terminal blocks. Use a crimper (not included) to install wire.

Use the ferrules for two wires to insert two wires into one terminal block.

Wire Ferrule Assortments

Keep a variety of ferrule sizes on hand. These ferrules add strength and stability to stranded wire, protecting it from damage. They also make it faster to insert the wire into terminal blocks. Use a crimper (not included) to install wire.

Barrel-insulated ferrules have a plastic cover to prevent short-circuiting with nearby wire. Nylon-insulated ferrules are more durable and resist chemicals better than polypropylene.

Use ferrules for two wires to insert two wires into one terminal block.
