Good fuse blocks but could use design improvements

Jim from Shakopee, MN on 6/3/2022

Verified employee review (What's this?)

I needed to install a fuse block between my JL Audio JD 1000 amp and my T spec distribution block since JL doesn't believe in installing fuses in their amps There are 2 very closely spaced mounting holes with 2 somewhat large screws provide. These holes are spaced too closely together for the large screws provided. They will certainly strip out the wood or metal which they will be attached to using the provided screws. I used two smaller O.D. screws in the hopes that it will not strip out in the future. Design flaw. The mounting holes should have been placed at opposite ends of the fuse holder. Plastic is a bit on the cheap side and when tightening the fuses the fuse block flexed slightly so don't overtighten. The price tag is a bit exuberant for the quality of this product but I like that the fuse is tightened down vs some of the fuse blocks I have purchased in the past. I have a Rockford Fosgate RFFAGU round fuse holder that the fuse fits inside a steel holder going to my battery with 80 amp fuse. The top and bottom of the round fuse fits in a hole and is not screwed down like the mini ANL so I will keep an eye on that and may replaced in the future. I have heard these round fuse holders may get hot and burn the plastic and possibly cause damage since they fit snuggly inside the holder but not tightened down there is a possibility of heat build up. I was going to give it 3 stars but decided on 4 because the ANL design is superior to round fuses.

Pros: mini ANL design allows fuses to screw down for maximum connection and safety

Cons: mounting holes spaced too closely together and a bit cheaply built for the money.

Received this item as a replacement to one I had ordered that had a crossed threaded allen-head screw. Excellent customer service! Product worked great and my addition to vehicle sounds amazing!

EFX DFB4 Delta Fuse Block is a an extremely good product. I thoroughly enjoy the added security. It holds Mini ANL Fuses, which is exactly what I needed. I was very impressed. I must admit that I was a little hesitant at first, but after receiving this item, I couldn't be happier with my purchase!
