Mul-T-Lock’s Classic platform is based on several special features:
- Mul-T-Lock’s unique telescopic pin tumbler mechanism, with internal and external pins – requiring the simultaneous alignment of both internal and external shear lines for the plug to rotate.
- A specially designed plug, which forms a spherical, 3-dimensional shear line with the top and bottom pins, within the cylinder body.
- Steel inserts with high drill resistance
- High pick and bumping resistance
- Optional side and back pins, specially suited for master key systems.
- A coded Mul-T-Lock key card supplied in every package, to enhance key security. Additional keys may be cut by authorized Mul-T-Lock dealers, upon presentation of the key card – in accordance with Mul-T-Lock’s official key cutting procedures.
The Classic platform meets the requirements of some of the most stringent European and American standards.
