CMK412 Push-in Lever Nut Electric Cable

The Push-in Lever Nut Electric Cable is an insulated wire connector designed for fast and secure electrical connections in commercial and residential lighting, digital signage, and general building systems. It serves as a modern alternative to traditional twist-on wire nuts, offering easier installation and more reliable performance.

This connector allows users to insert stripped wire ends directly into ports without the need for special tools. An internal spring clamp automatically locks the wire in place, or a lever mechanism may be used for added security. The CMK412 Push-in Lever Nut Electric Cable supports one wire per port and is typically reusable with solid conductors of equal or smaller gauge.

Its design simplifies installation, saves time, and enhances safety. 

CMK662 lever lock wire connectors

Lever lock wire connectors for quickly and securely joining both solid and stranded wires. Featuring an optimized spring design delivers easy open levers and strong bite to deliver fast and secure connections. Install with confidence - the transparent housing enables visual inspection of work. Reusability of solid or stranded wire and dedicated test ports make servicing connections a snap. Compatible with standard wire ranges, the 2-port, 3-port, and 5-port options empower you to tackle just about any job.

Color coding and transparent housings allow for quick identification and visual confirmation of a secure connection. As an innovation over older screw-type or splice connectors, the CMK662 lever lock wire connectors

compact form factor also helps streamline wiring layouts in tight spaces.

CMK421 push in wire connector

The CMK421 Push-In Wire Connector is a dual-entry connector designed for quick, safe, and efficient electrical connections. Its two-way structure allows connection from both ends, making it ideal for joining multiple wires or linking circuits in a straight line. No twisting or tools are needed—just strip and push in the wire. An internal stainless steel spring secures the wire firmly, ensuring a strong, vibration-resistant connection.

Compatible with solid and stranded wires, the push in wire connector is perfect for lighting systems, distribution boxes, and tight installation spaces. Its compact size saves space, while the transparent, flame-retardant PA66 housing allows for easy inspection and safe use. Reusable and easy to install, it’s a practical solution for fast, reliable wiring in both residential and commercial applications.

CMK420 DIN Rail Quick Terminal Block

DIN rail terminal blocks are attachments that protect electrical equipment by preventing short circuits and excess current surges across connecting wires. They are made from plastic or other insulating materials. They provide a safe interface between the components on the DIN rail.
DIN rail terminal blocks are one of the most widely used types of electrical connector in industrial environments. They join a single wire to a single circuit in their most basic form, forming a single-pole connection.

Electrical terminal block connectors create semi-permanent links, allowing power to pass around a circuit. The wiring can be repaired, replaced and changed with relative ease.
