Another device used to get confession from the convict, usually use to extract name of the conspirator. It was said to be the most painful torture.

It was a wooden frame usually above ground with two ropes fixed to the bottom and another two tied to a handle in the top.

The idea behind the rack was to tie down a victim while a mechanical pulley arrangement enabled torturers to pull on the ropes. Under such torment, the victim had his body stretched until the joints were pulled from their sockets.

The torturer turned the handle causing the ropes to pull the victim's arms. Eventually, the victim's bones were dislocated with a loud crack. If the torturer kept turning the handles, some of the limbs were torn apart, usually the arms.
