This special bulkhead connector will prevent battery cable shorts where the cable passes through a body panel. Simply install the connector in your panel and connect your battery cable on either side.
The heavy-duty brass stud assembly has a thick plastic collar to insulate power from the surrounding panel. The collar is threaded to accept a special mounting nut (included), which holds the connector firmly in the panel. Mounts in a 1 1/4" hole (flange OD 1 9/16"). Accepts 3/8" ring terminals. Includes 3/8-16 UNC nuts.
