Notes: Littelfuse In Line MIDI Fuse Holder M5 nut w/insert and cover. The Inline MIDI fuse holder is designed for use with bolt down MIDI fuses. It may be installed direcly inline with the cables with no mounting required. The Inline MIDI fuse holder can be used with heat shrink tubing for applications requiring more splash resistance. The curved design of the cover aids in prevention of tube-splitting during application.
