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.

& architectures, and serve as convenient power tap points. Feed-
thru versions enable firewall-mount applications and help reduce
wiring costs and overall space required for cable routing.
Junction blocks are available in various thread sizes and lengths.
Lock washers and nuts are included with each block.
