When you’re making dozens of electrical connections throughout the day, the last thing you want is a wire connector that slows you down. Whether you’re working inside a crowded electrical box, dealing with multiple conductors, or installing wiring on a large commercial job, having the right connector makes a difference. That’s where the new Klein Tools Wire Connectors come in.
Klein Tools is expanding its electrical installation lineup with new winged and skirted twist-on wire connectors designed to make electrical work faster, easier, and more efficient. Featuring curved wings for added leverage, quick-bite springs for secure connections, and hex tops compatible with nut drivers and power tool accessories, these connectors bring practical improvements to an everyday electrical essential.
With six options covering wire ranges from 22 AWG to 6 AWG, electricians can find a connector suited to a variety of residential, commercial, and industrial wiring applications.
What’s New About Klein Tools Wire Connectors?
At first glance, wire connectors might seem like a simple product, but Klein Tools has incorporated several features that help make installation more convenient without sacrificing dependable performance.
Quick-Bite Spring for Secure Connections
A reliable electrical connection starts with a connector that properly grips the conductors.
The integrated quick-bite spring is designed to grab wires quickly and securely, helping electricians create consistent connections while keeping installations moving.
This feature is especially useful when working through multiple connections during rough-ins, renovations, or electrical maintenance.
Hex Tops for Faster Installation
One of the most convenient additions is the hex-shaped top.
Instead of relying entirely on hand twisting, electricians can use compatible nut drivers or power tool accessories to install these connectors.
For professionals installing connectors throughout the day, this provides another way to streamline repetitive work.
Flexible Skirts for Tight Electrical Boxes
Klein Tools’ skirted wire connectors take things a step further.
The flexible skirt helps protect against flash-over while allowing the connector to fit more easily into tight electrical boxes.
For electricians working with crowded junction boxes and multiple conductors, this added flexibility can make installation and wire management more convenient.
Built for Demanding Jobsites
The connectors feature durable polypropylene construction, with the skirted versions incorporating flexible TPV material.
They are also UL Listed as pressure-type wire connectors, with a maximum operating temperature of 221°F (105°C) and voltage ratings of up to 600V for building wires or 1,000V for signs and luminaires.
These are not weatherproof connectors and are not intended for underground use.
New Klein Tools Winged Wire Connectors
