Aluminum Splices / Reducers 4 Screw

4-Screw Aluminum Splices & Reducers

Our collection of 4-screw aluminum splices and reducers includes heavy-duty mechanical connectors designed for joining conductors of the same size or transitioning between different conductor sizes. These connectors are commonly used in commercial, industrial, utility, and institutional electrical systems where reliable, high-capacity conductor splicing is required.

The four-set-screw design provides increased clamping force and excellent conductor retention, making these connectors well suited for larger wire sizes and high-current applications. Manufactured from high-strength aluminum alloy and commonly finished with electro tin plating, they offer excellent conductivity while helping resist corrosion in demanding electrical environments.

Built for Large Conductors

Compared to standard 2-screw splice connectors, 4-screw aluminum splices provide additional mechanical strength and improved contact integrity for larger conductors. They are frequently used on feeder circuits, service entrance conductors, power distribution systems, switchboards, transformers, and other equipment handling higher electrical loads.

Splice or Reduce Conductor Sizes

These mechanical connectors are designed to either join conductors of the same size or reduce from a larger conductor to a smaller one. They are an excellent solution for service upgrades, equipment replacements, conductor extensions, repairs, and electrical distribution modifications where dependable electrical continuity is essential.

Dual-Rated for Copper and Aluminum Conductors

Many 4-screw aluminum splices are AL9CU dual-rated, allowing them to terminate both copper and aluminum conductors when installed according to the manufacturer's specifications. Their tin-plated aluminum construction helps minimize contact resistance while providing long-lasting protection against corrosion.
