Description
Our 3/8” pass-thru stud has a high electrical rating and low
resistance due to a large cross-sectional contact area. It also uses
highly conductive materials to outperform the competition.
This pass-thru stud boasts high installation torque values to allow
the use of large cable sizes for high current applications. Stud caps
are included to protect from accidental shorts.
The pass-thru stud is available with red or black body and stud cap
to help color-code circuits in the vehicle. A plastic body locknut
ensures quick and easy firewall-mount installation without the
need for additional hardware.

Junction Blocks are used as electrical connection points for the
distribution of power or ground. These blocks can simplify cabling
& architectures, and serve as convenient power tap points. Feedthru versions enable firewall-mount applications and help reduce
wiring costs and overall space required for cable routing.
