This is a ANL fuse holder to match my Shunt Holder (that's why its longer than it needs to be - I installed these side by side). I adapted it to the smaller fasteners I preferred to use. The mounting holes are sized for rivets. I could make this more screw-friendly if requested.
Tip: Use washers to level out your fuse if you decide to mount it on top of the stack (which has merit as its more operable).
