The Heavy-Duty Automotive Relay Base is a professional-grade, interlockable socket designed for secure and organized relay installation in vehicles, machinery, and custom electrical panels. Molded from rugged, high-impact black composite, this base includes an integrated mounting tab that allows you to easily bolt or screw the assembly directly to a firewall, chassis, or under-dash panel.
Designed to accommodate standard 4-pin and 5-pin automotive relays.
