5/16 PASS THRU POWER POST RED

5/16″ Pass-Through Power Post Red – Bulkhead Positive Supply Post for Motorsport Firewall Installations

The 5/16″ Pass-Through Power Post Red is a bulkhead-mount positive supply distribution post for professional race car firewall and panel pass-through power distribution. Colour coded red for positive voltage identification and featuring pass-through access on both sides of the bulkhead or firewall, this post allows the main positive power supply from the battery to be cleanly distributed to cockpit-side circuits without separate firewall connectors or additional distribution hardware in motorsport electrical builds across Norway, Sweden, and Denmark.

Clean Firewall Power Management in Race Cars

The firewall pass-through is one of the most important design decisions in a professional race car electrical build. Using a pass-through power post instead of a bare wire through a grommet provides a proper, serviceable, and mechanically secure power distribution point at the firewall boundary. The red pass-through post gives the build a professional appearance, makes the positive main supply immediately identifiable during service, and provides a reliable stud termination point for both engine bay and cockpit positive circuits at a single, accessible location.
