Battery terminal connector ARCO P4573FR 1" x 22 mm arc-style

ARCO P4573FR 1" x 22 mm arc-style battery terminal connector is engineered to provide a reliable mechanical and electrical connection for batteries with a 22 mm post. The clamp-style design secures cable lugs and bare conductors while delivering consistent conductivity for vehicle, marine and stationary power applications. Constructed to fit a standard 1-inch (22 mm) terminal interface, the connector facilitates straightforward installation and dependable current transfer in environments where a compact, robust battery clamp is required.

Advantages

The arc-style geometry concentrates contact force around the terminal post to reduce resistance and improve stability under vibration. The clamp accepts a range of cable sizes and lug types for flexible wiring options. Its metal construction provides good conductivity and mechanical durability, while the compact form factor allows use in confined battery compartments. Designed for repeated connections and disconnections, the connector supports maintenance tasks without degrading contact quality.

Suitable for

• Automotive battery posts with a 22 mm (1") terminal
• Marine battery installations subject to movement and vibration
• Industrial and stationary battery banks and power distribution systems
• Replacement or upgrade of existing 22 mm battery clamps

Key specifications

• Terminal post diameter compatibility: 22 mm (1")
• Connection style: arc-style clamp for post terminals
• Material: conductive metal alloy for electrical contact and mechanical strength
• Cable attachment: accepts crimped lugs and bare conductors secured by clamp fastener
• Typical applications: automotive, marine, industrial battery connections

How to use

Ensure the battery is disconnected or the vehicle/equipment is powered off before installation. Position the connector over the 22 mm terminal post so the arc-shaped clamp fully engages the post. Insert the cable lug or conductor into the clamp area and tighten the fastener to secure the conductor and establish a firm electrical contact. Verify that the connection is tight and that no bare conductor is exposed where it could short against nearby metal. After installation, check the connection under normal operating conditions to confirm stable contact and absence of excessive heating.

Usage recommendations

For reliable long-term performance, use appropriately sized cable lugs or properly prepared stripped conductors, apply correct torque to the clamp fastener, and periodically inspect for corrosion or looseness, particularly in marine or corrosive environments.
