    I found an old battery terminal I already had could be used to turn the output lug 90 degrees on its side. This one I currently have here is a negative, meaning it is smaller, but I can enlarge the opening for a positive post, would save me $10 or so.

    Then I found 'military' battery connectors also do that.
    Idea being if you wanted a MRBF terminal fuse to fit under a battery box lid, these exist to make that happen. without having to make your own L bracket. Of course have to have a conical post, otherwise you have to make the L bracket from copper plate. I bought a 1/8 " thick large sheet copper plate years ago, of 4 by5 feet for $40 as a remnant at a shop. I used that to make a grounding buss bar for the boat 3 layers thick, with the layers soldered together. And SS bolts tapped and threaded for lugs. It works very well. The oak wood piece was countersunk to fit bolt heads and pained black. It is one layer thicker than needed. You need a large acetylene torch to solder big pieces of copper, it just sucks the heat away from the flame. So, yes, I could make my own L bracket.

    And you can buy them with rubber covers


    Such as these. Lead is easier to rework. A negative post is not as useful as positive if you would use these for a MBRF terminal fuse.

    mbrf-too-tall.PNG Except it may not fit in the box with the battery box lid on, when using a MBRF terminal fuse. I know it does not on mine. Only solution is to flip it over 90 degrees, or dont use the box lid.

    example pic, notice how much taller the MRBF holder sits?
    If I did that on mine, I would have to hack away the box lid to fit it.
