ok that is an ANL fuse, those are for high amp systems, is the fuse holder that you have, is it an ANL or a midi. because they accept different style fuses. If you have a midi fuse holder than you need a midi fuse. If you have an ANL fuse holder you need an ANL fuse. there is also AGU fuse and fuse holder, those are the glass cylinders. it all depends. buy the fuse that fits the housing.
If its anl get this

this fuse holder requires rings terminals to hold the wires on the posts and the fuse goes in between.
