Black Insulated In-Line Splice 2 Set Screws

Overview: In‑Line Splice with Two Set Screws

This sub‑collection focuses on mechanical splice blocks designed for in‑line runs (conductors enter opposite ends) and featuring exactly two set screws—one per conductor. The rugged black insulation makes these splice connectors a professional‑grade choice for panelboards, feeders, troughs, and distribution systems.

Key Benefits & Features

• Professional reliability: In‑line configuration simplifies routing in power distribution systems while maintaining a secure mechanical and electrical connection.
• Two set screws: One screw per conductor ensures proper clamping and creates a consistent, re‑enterable splice point.
• Durable insulation: Black high‑dielectric rubber or vinyl coating resists abrasion, chemical exposure and is designed for use in industrial and commercial electrical environments.
• Dual‑rated CU/AL compatibility: Many blocks support both copper and aluminum conductors, reducing inventory complexity.
• 600‑Volt system rating: These in‑line splice blocks are often rated for 600 V and designed for power distribution use.
• Inspection‑friendly design: Compact form, factory insulation, and clear configuration labeling make these connectors faster to install and easier to inspect.

Typical Applications

• Feed‑through splices in panelboards or switchgear where conductors enter one side and exit the other.
• Taps or splices on feeders in troughs, ladder racks, cable trays or inside large junction boxes.
• Commercial and industrial installations and retrofit jobs where conventional tap methods are replaced with mechanical insulated splice blocks.
• Overall installations where standard black insulation is preferred and visual transparency is not required.

Note: These connectors are insulated mechanical splice blocks—not ring/spade terminals or standard lug‑style terminations. They are optimized for larger conductor sizes, in‑line routing, and industrial/commercial power distribution rather than low‑voltage control wiring.

Selection Checklist

1. Conductor type & size: Verify whether copper, aluminum or both; check the supported wire gauge range and port size.
2. Entry layout: Ensure the in‑line style fits your run – conductors entering opposite ends rather than single side or multi‑port branching.
3. Set screws & materials: Confirm the number of ports and set screws (2 screws = 2 conductor ports), and that the body is aluminum alloy and properly treated for corrosion/oxidation.
4. Insulation rating: Confirm 600‑V rating and temperature range.
5. Service/inspection access: Make sure the module is accessible for future maintenance or inspection—especially in embedded troughs or large enclosures.
