10mm (3/8") Positive Insulated Power Junction Stud – Red
Heavy-Duty High-Current DC Terminal Post for Marine & 4WD Systems
Streamline your high-amp 12V and 24V power distribution with the 10mm (3/8") Red Insulated Power Junction Stud. Designed for heavy-duty automotive, dual-battery, 4WD, and marine installations, this robust terminal post provides a secure, central connection point for joining large-gauge battery cables, connecting auxiliary feeds, or extending main power leads.
Built with a high-tensile stainless steel stud and a glass-filled nylon insulated base, it offers exceptional mechanical strength, heat resistance, and chemical durability. The vibrant red color ensures instant positive polarity identification, while surface-mount screw holes allow for clean, rigid mounting against firewalls, battery boxes, or canopy walls.
