Instructables
This instructable shows you how to make a ratchet to box keys if you're in an emergency.
All you need is 3 pieces from you ratchet kit:
An extension;
A cardan (most kits have write "universal joint");
And finally the box key you need.
To assemble connect the box key to the cardan and the cardan to the extension.
Now bend the cardan 90 degrees while putting one of the talls in the cardan in one of the cardan's reentrance, like in the picture and you are done!

I hate universals. Try to put any torque on em when they're bent more than 30 degrees and the damn pin snaps. Swivels are the way to go.

looks more like a breaker bar than a ratchet but thank you for sharing
