We sell fuse pullers for cartridge fuses with a 6mm diameter. Fuse pullers make it easier to remove a fuse from a holder. They are invaluable when the terminals of the fuse holder are tight fitting or when space outside the fuse box is limited. The also reduce the change of touching any live circuits that may be in the area of the fuse. Fuse Pullers can often be used to insert a fuse as well.
