Ideal for tradespeople, OEMs, and facility maintenance teams, this connector offers a high-quality bi-metallic design with tin-plated finish and insulating cover — all rated for 600 V use. With easy installation, corrosion-protection, and a trusted brand backing, it ensures a secure and durable connection you can count on.
Key Features
- Compatible with both copper and aluminum conductors — tin-plated barrel is dual-rated for AL9CU applications.
- Offset solid pin design: 4/0 AWG conductor → 2/0 solid pin size.
- Pin diameter: 0.42″; Pin length: 1.27″; Total length: 2.78″.
- Rated for up to 600 Volts nominal.
- Barrel coated with oxide-inhibitor to minimize corrosion and extend service life.
- Includes EPDM rubber insulating cover for additional mechanical and environmental protection.
- Die index and crimp marks on barrel facilitate correct installation and ensure industry-standard crimp compliance.
- Color coded: White (for the 4/0 → 2/0 variant) — helps with system identification and grouping.
- UPC: 601986909877.
- Part Number: 90987 (Morris Products).
Applications
This connector is ideally suited for commercial and industrial power distribution systems, including switchgear, bus-ducts, motor control centers, generator terminations, and any location where aluminum cables transition to copper solid pin terminations. Its dual compatibility with aluminum and copper makes it an efficient choice for retrofits and new installations alike.

Installation Tips
- Ensure the conductor is properly stripped and cleaned of oxidation before crimping for maximum contact.
- Use a crimp tool rated for the 4/0 AWG size and follow the die index or crimp marks on the barrel for correct positioning.
- After crimping, apply appropriate torque and inspect the insulation cover to confirm it fully encloses the termination.
- In aluminum conductor applications, ensure an approved aluminum anti-oxidant compound is applied if required by the installation specification.
- Verify system voltage and environment to ensure 600 V rating and ambient conditions are within spec.
For demanding installations requiring a robust, dual-rated terminal connector engineered by an industry leader, the Morris Products 90987 offers outstanding value, performance, and peace of mind.
