Fastronix 3/8" Terminal Covers

These worked perfectly for the inverter upgrade in my Nissan Xterra. They are soft, and can stretch over the input studs easily. As soft as they are, they are pretty durable in that they didn’t tear when I installed them. I don’t know if I’d use them in an under hood environment, but for this application, they worked nicely.

Used with matching feed through bulkhead studs. Nice finished look and provides necessary insulation. Over priced for what it is, but do it cheap or do it right are never on the same page.

Worked as intended.

I think these are well made and I'm using them on an off-road / trail truck to clean up some of the terminations as to protection and coverage so no shorts and grounding etc.

Color and thickness is sufficient. Very flexible

I used these to cover the 3/8" terminals on the back of a 6 pole kill switch. They fit over 1/0 wire and worked perfectly.

Used this during a jumper post location install in a 36 Ford Coupe to allow for car to be jump started without having to take seats out of car to get to battery.

I am glad that I purchased the 3/8" version to ensure it would fit over my 2/0 AWG cables, if not it would have probably been too snug to maneuver over the crimp connection and heat shrink. I used these on several 2/0 AWG cables some with 5/16" ends and a couple with 3/8" ends.For connections directly to the battery terminal it provides nearly complete coverage, for many of my other locations it can only cover a portion (as expected). The product was flexible enough to maneuver as needed with some patients and force required to get it back over the end of the heat shrink when moving into the final position.The my initial perception of the product is better than expected and I appreciate the added protection against shorts that it provides even in the less than ideal locations.

finished off the install

These fitted nicely over some through bulkhead studs. The delivery was a bit tardy but that is probably to be expected given they had to come from the States and it is a busy time of year.
