Evva 3KS Plus Cylinders

The key is reversible meaning it can be inserted either way making operation simple. The 3-curve design incorporates additional security ensuring the system is suitable for deployment in the largest and most complex master key systems. Unlike most master key systems that rely on spring pressure in the cylinder, the 3KS Plus sliders (locking pins) inside the cylinders are actively moved by the tracks in the key. This active operation means 3KS Plus will outperform all others in challenging environments be they dirty, dusty or salty.
