Cover too loose.
Size: 300A Fuse Holder
Nice looking, decent quality, versatile for different gauges. My only complaint with this holder is the cover doesn’t stay on very well, bought 3, and all 3 pop off easily, you will need to zip tie on.

Solid choice for fuse holder
Size: 300A Fuse Holder
It’s awesome, solid connections for running 0 gauge wire. No issues after using for months! Might upgrade to using 0 gauge wire ferrules to use with this but for now everything is working well.
