WORTH THE MONEY, dont spend the unnecessary extra money this will do!
Size: Single, Style: 1-Way 200A Fuse, Color: Square ANL Fuse Holder, Size: Single, Style: 1-Way 200A Fuse, Color: Square ANL Fuse Holder
I'm very happy with these I normally buy Knukonceptz they have great product and always have one of their fuses. But I needed to pinch pennies more so in decided to buy these. These are really really solid. Some said the plastic was junk but I think they must not know what they're doing bc they snapped to place properly. They are super solid my 0 gauge fit in it like a glove as should, screwed in well. And is doing its job. Would buy again for sure!
