ASSA Twin 6000
The Twin (or Twin 6000) is a UL 437-rated pin-tumbler lock made by ASSA. The 6000 is part of the Twin series of locks that use pin-tumblers and a sidebar to provide two layers of security. The 6000 is the original Twin series model. Later systems made by ASSA built upon the 6000 to provide increased security against manipulation and key duplication.
