ASSA Twin Maximum+

Protected by patents and design.

Each ASSA Twin Max+ key has two sets of cuts: the edge cuts, and the side-bar cuts, effectively combining two keys into one. This combination creates an ultra-secure key that can only be reproduced with authorization using special machinery. The undercut milling in the middle of the key thwarts casting attacks, and makes 3-D printing exceptionally difficult. Coupled with close-tolerance precision machining, these keys and locks mean that no one else, but you, has keys to your property.

Better than Medeco.

ASSA Twin Maximum+ lock cylinders are all equipped with 6 inline, spooled, pin-tumblers, countermilled chambers, and an additional sidebar locking mechanism. These locks boast excellent pick resistance by combining two high-security lock designs into one ultra high-security system. With additional hardened-steel inserts, and solid nickel-silver pins, you can rest assured that this lock will not be drilled with ease. These features are stronger than Medeco locks, making it the superior choice.

Guaranteed Tough.
