    Wire Ferrule Assortments

    Image of Product. Front orientation. Terminals, Ferrules, and Lugs. 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.

    Heat-Shrink-Insulation Terminal and Splice Kits

    For use where water and contaminants are a concern, the terminals and splices in these kits have insulation that shrinks and creates a tight seal when heated. Use a crimping tool (included with some kits) to install wire.

    Quick-Disconnect Terminal Assortments

    Image of Product. Front orientation. Terminals, Ferrules, and Lugs. Quick-Disconnect Terminal Assortments.
    Install, extend, or rewire a circuit without hunting down new terminals. These assortments include quick-disconnect terminals for most small and medium wire gauges. Labels in the lid include our part numbers, so it's easy to replenish your assortment.
    These terminals pair with other quick-disconnect terminals, so you can pop them apart whenever you need to break a connection. Attach your wire with a crimping tool to avoid a damaged barrel and loose connection.
    Vinyl Plastic Insulation—Our basic insulation, vinyl prevents the wire from short circuiting and won’t break down from dirt, grime, and occasional twists and tugs.
    Nylon Insulation—In addition to preventing short circuits, this wear-resistant insulation protects wire from vibration and rubbing against nearby edges.
    Fully Insulated—Plastic covers the entire surface of the terminal, including the connection tab, so there’s no exposed metal to spark or short circuit when connecting to another terminal.
    Barrel Insulated—The wire is covered in plastic so it won't short circuit if touched by a screwdriver, nail, or another live wire.
    Noninsulated—The basic, economical option when short circuits from nearby wiring aren't a concern.

    Ring terminals encircle the whole the screw shank, so they stay put better than spade and hook terminals when vibrated or pulled. Attach wire with a crimping tool to avoid a damaged barrel and loose connection.

    Covers

    Lay the main wire into your tap on the first try instead of poking and threading. The tap wire connects parallel to the tap or at 90°, so the tap will slide into your setup at different angles. Strip both wires and slide off the screw plate before installation. Tighten the set screws onto both wires for a secure connection.
    Covers—These covers fully insulate the tap so moisture can't reach the wire. They snap shut so you don't have to tape them down.
