Works great! Super heavy duty, almost overkill
Color: 600A B&R
Very heavy duty! Used as a battery relocation point in my truck. Have this mounted where battery is supposed to go. I have a few 2/0 wires going to this without issue. I did have to cut the covers back a bit with a dremmel to get all these large wires to fit.

So well made!
Color: 400A B&R
This is a very heavy duty high quality bridge. If dealing with high DC loads this is Your goto right here, just check Your measurements & have at it.

Worked perfect for my cargo trailer needs
Color: 400A R&R
Worked great to connect my battery and winch relays to. I purchased one on sale and it was a tremendous value, only catch was both sides were red signifying a positive terminal. I simply spray painted one side black so now the positive and ground side are evident

Great quality part!

Super heavy duty and probably overkill for my car but I’m sure it will never be the weak link i. my install.

Good qaulity
Color: 600A B&R
I’ve had them sitting in the sun for about 6 months on my boat and the plastic hasn’t even started fading yet, thick plastic, sturdy lugs, quality product.

Stud size is WRONG on the product page.
Color: 400A B&R
The studs are NOT M8, they are M10. The description says they are AVAILABLE in M8, but I don't see a way to ORDER it in that configuration. What showed up is of good quality, but it meant I had to purchase M10 size wire lugs, when everything else in my battery wiring is M8. The product is of good quality construction, though. ... show more
