Cawi 2618 - 1819 eight, nine, & eleven lever Pick and Form decoder.

These Cawi locks have levers that are not individually sprung. When tension is applied with a two in one pick it is difficult to control and maintain lever position.

The pick and form system has been designed to over come the picking difficulty.

The system has a setting key that allows levers to be set to different key height positions.
Whilst held in these positions another part of the tool is able to be introduced into the lock in order to test each lever.

The levers that register as being incorrect are then set to a different key height with setting tool until their true position is found.

A skilled user should be able to decode and open a 9 lever lock within 30 minutes.
