SPL Series Lever Nut Wire Connectors

The SPL Series Lever Nut Wire Connectors are professional-grade compact push-in terminal blocks designed for fast, reliable, and tool-free electrical connections in residential, commercial, and industrial applications. These innovative connectors combine the convenience of push-in wire insertion with the reliability of lever-release mechanisms, allowing quick connections for solid wires while providing secure clamping for stranded and flexible conductors when using the lever.

Each connector features a spring-loaded push-in mechanism that accepts solid wires directly without any tools, while the orange lever actuators enable easy insertion and secure clamping of stranded or flexible wires. Simply strip the wire to the appropriate length, push solid wires directly into the terminal, or lift the lever for stranded wires, insert the conductor, and release the lever to achieve a gas-tight, vibration-resistant connection. The transparent housing provides visual confirmation of proper wire insertion and conductor positioning.

Available in multiple configurations from standard 2, 3, and 4-port models to innovative mixed-capacity variants (SPL42, SPL62, SPL93) that combine different wire-per-port capabilities in a single compact connector, the SPL series accommodates diverse wiring scenarios. The mixed-capacity models allow efficient junction configurations where some terminals handle multiple branch circuits while others manage single connections. Ideal for lighting installations, electrical distribution panels, junction boxes, industrial controls, HVAC systems, and renewable energy installations where reliable, reusable, and space-efficient wire connections are essential.
