## Questions & Answers

**Q: Can I get 2 red terminals?**
A: I’ve never seen them sold separately. Maybe try to reach the manufacturer, Fastronix Solutions and ask them.

**Q: Any way to use these with Lithium Lifepo4 cells with M6 size terminals?**
A: The Internet half whole size is the size of the red bushing going through the metal wall to insulate it from the metal that the 2 terminals on each side will fit your 4 mm cable

A: As long as the cables have a 3/8" lug on them you can use this part to pass the power to your new battery location in the trunk.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Solid construction
*by D***L on June 15, 2024*

I need to provide pass-through DC connection in an outdoor shed with plywood siding. Drilling a hole with a hole saw is easy. The thick plastic shank and flanges will seal the hole and protect the connection inside and out. The slight issue (-.5 stars) is that the bolts are longer than necessary. Wire connections will be made with flat ring connectors. Torquing the nut down requires a deep-well socket which I happen to already own; however, this would not be necessary if the bolt were 1/4" shorter on both ends.

### ⭐⭐⭐⭐⭐ Seems good quality
*by A***R on December 8, 2024*

So far definitely work as described. Only down side is the size of the hole you have to drill but it is what it is.

### ⭐⭐⭐⭐⭐ They let you access your battery from an enclosed box.
*by G***T on February 17, 2023*

They are beefier than they look in person. They use the same size holes as any other Cigarette lighter or USB PowerPoint that I've purchased in the past. You will need 4 cables to use them. Two cables that connect to the battery inside the box. And another 2 sets of cables to connect the outside receptacle to your devices. They are extremely well made. They don't feel cheap at all. You can mount them on metal or plastic. It doesn't really matter.
