The 406-Series ‘Winged’ Safe Lock is the winged lock option that again targeted the Grade-A Security rated market of the day. Again, this lock is based on the 400-Series ‘open-gate’ pick resistant serrated lever.
Open Gate Lever
The 406-Series ‘Winged’ Lever Lock consists of two types of surrated levers. (4) open gated levers and the top (2) racked levers make up the lever pack in this lock. The lever spring is shortened so as keep tension due to the positioning inside the case. The brass 102-Series key gauge will also assist in key decoding.
