## Questions & Answers

**Q: How big is the head of the boot? heavy duty ftz 1/0 power lugs are over 3/4" wide at the flat part. i'm wondering if they will fit.**
A: The I.D. of the terminal end of the boot is 11/16". These boots do stretch a little bit but that lug is probably a little large for this boot.

**Q: will they fit 4/0 cable**
A: The openings on each end are 5/8". The cable will fit through that but it may be tight with the battery cable ends and may require some trimming.

**Q: Does fastronix make a boot that works with the high current 3/8" thru panel battery terminal connectors? i tried these , but they don't work.**
A: I've used both those pieces. I ended up warming the covers for pliability, and stretching the boot around the terminal.
Has not caused any problems after a year.

**Q: Will these fit 1/0 cable?**
A: Yes these will fit 1/0 cable.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Flexible and easy to use
  

*by J***E on Reviewed in the United States on 18 June 2021*

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.

### ⭐⭐⭐⭐

### ⭐⭐⭐⭐ 







  
  
    Fit for purpose
  

*by B***Z on Reviewed in Australia on 15 December 2021*

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.
