[Spoony73]

Hello

I am trying to give my dormobile bunk bed some tlc but can seem to find the correct tool believed to be a Allen key to remove to canvas from the poles so I can get the all a good clean.

Any one know what it is I require please ?

Many Thanks

Simon

The canvas is held onto the poles by little strips of plastic and pop rivets. They just need drilling out.
