The EVVA system uses a unique pinning system using sliders to activate a control bar with no traditional top pins. In addition, broaching sidebars are used to create multi-broached key systems allowing qualified locksmiths to install the largest of key systems

EVVA is SCEC Endorsed for Intruder Resistant Applications. The strong, one-piece metal key ensures against expensive on-going key replacement, and the absence of pins and springs provides unmatched resistance to wear and corrosion of internal parts. 

EVVA has high-security, anti-pick, anti-bump sliders made from Teflon impregnated nickel silver. They are protected by hardened sidebar blocking pins and a key control hook pin. In the front of the cylinder we have hardened steel pins to protect the cylinder against attacks.

Compatible with all Australia commercial locks and padlocks.
