What fuse or component needs to go inside this 110v site transformer?

I have a 110volt construction site transformer, the big yellow ones.there are two black holders with red parts inside; where there are missing components that I assume are fuses or circuit breakers. Does anyone know what they are. The blades holders are off centre unlike normal fuses.
TIA.

What about a "fusepuller"?
For that style, the cover IS the fuse puller.

"Lawson Clipfit" are another type in that style:

Whether its those, the GE ones that KMoffet posted or some other type, the fuse body latches in to the lid and its blades or tags fit directly in to the holder, rather than the lid having separate electrical contacts.

The simplest fix is probably just to buy two new NS type fuse holders and replace the existing ones.

These are the fuses to fit, by the way:
 
Thanks for that. US and uk differences. House phone distribution in the uk is really wierd.

We have a wierd thing that the meter socket has to be from a certain manufacturer AND have the local power companies sticker on it. the meter socket can be bought locally at any supply house.

The offset style, I guess, is a deterent. The US penny coin could be used to replace an edison based fuse. You can't use a flat bar of metal to easily replace an offset fuse. The edison based fuse could be replaced by a light bulb to make it easier to find a shorted device.
 
what you were supposed to do with the edison socket, is screw a light bulb (incandescent), and begin unplugging things from wall sockets... when the light bulb stopped glowing at full brightness, you had found the shorted device... if the bulb remained lit after everything has been disconnected the problem is in the wall, so you could begin disconnecting wirenuts to localize the short.
The US penny coin could be used to replace an edison based fuse.
in most cases that would be the most expensive penny you ever spent... if the short was still there, you risked burning down your house...

The fuse in question isn't a domestic one, it's a special industrial fuse - I've never even seen one.

European "bottle fuse" (Diazed) holders are similar to the US Edison style fuse holders at a glance.

But, when they are installed, they are supposed to have a ceramic "gauge ring" insert fitted, that prevents a a short from such as a coin and only allows a fuse of up to the correct current rating to be installed, as each different rating from 6A up has a different diameter "neck" to the bottle shape:

There are a ludicrous number of different types / style of fuses in use, in different machines from different eras and different countries.
