Mul-T-Lock MT5+ Patented Key Control System

Показать описание

MT5+ keys combine patented technology and advanced key control for enhanced security. Telescopic pins create a dual shear line while the innovative, patented Alpha Spring located at the tip key, engages a unique pin at the rear of the locking mechanism to create an additional shear line for enhanced intrusion resistance. The side-bar mechanism also allows for millions of possible combinations making MT5+ an ideal choice for complex keying needs. In addition, MT5+ keys control unauthorized key duplication via a coded magnetic duplication card - which can only be read by a dedicated Mul-T-Lock key cutting machine at an authorized locksmith.
