Black Insulated 2 Conductor Dual Entry Splice 4 Set Screws

Overview: Dual Entry 2-Conductor Splice with Four Set Screws

These connectors are engineered for applications where two conductors must be joined and the wiring layout requires conductors to enter from both sides. The four-set-screw configuration (two screws per conductor) offers superior mechanical connection and is particularly suited for heavy-duty feed-through or tap splices in industrial, commercial or high-vibration environments.

Key Features & Benefits

• Dual-entry configuration: Conductors enter from opposite sides for efficient routing and optimized layout in panelboards, switchgear, or large junction boxes.
• Four set screws: Two screws per conductor provide increased clamping force and improved reliability under mechanical stress or vibration.
• Durable black insulation: High-dielectric and impact-resistant coating designed for harsh environments, abrasion, and industrial use.
• Copper/Aluminum compatibility: Many manufacturers offer dual-rated CU/AL models to support mixed-metal installations and simplify inventory.
• 600-Volt system rating: Built for power distribution circuits, feeders, branch taps, and professional installations rather than low-voltage control wiring.

When to Use These Splice Blocks

• Splices or feed-through runs where conductors enter one side and exit the other, and enhanced clamping is needed
• Installations in panels, troughs, or heavy-duty enclosures where vibration, high current, or mechanical stress exist
• Retrofit or upgrade projects in commercial or industrial settings where reliability and inspection-friendly wiring is required

Note: These units are insulated mechanical splice blocks for two conductors—not ring/spade/fork terminals and not device-lugs. They are optimized for power-distribution wiring and not suited for low-voltage control or signal circuits.

Selection Checklist

1. Conductor material & size: Confirm copper, aluminum, or dual-rated; ensure the block supports your wire sizes.
2. Entry layout & port style: Dual entry means wiring from both ends—make sure the splice block suits your wiring routing.
3. Clamping configuration: Four set screws (two per conductor) required when higher mechanical or electrical stress is present.
4. Voltage & listing: Ensure 600 V rating and the appropriate listing (e.g., UL or CSA) for your application.
5. Installation environment: Check ambient temperature ratings, insulation material suitability, clearance for re-entry or inspection.
