Mul-t-lock MT5+ Hercular Single Cylinder Deadbolt w/ Thumb Turn - Black

The new MT5+ features not only a double-sided flat key but also 3 active locking mechanisms. The locking bar mechanism is one of the three technologies featured in the MT5+, and the correct alignment of the top bar pins depends upon the correct combination key being inserted. The new-generation product is also based on a new configuration of Mul-t-lock's well-honed telescopic pin technology.

The tip of the key has a revolutionary mobile interacting spring - the Alpha Spring. The Alpha Spring engages a unique pin at the rear of the mechanism, creating another shearline. All MT5+ products have a double-sided unique MT5+ key, with one set of cuts for the telescopic pin mechanism and the other cut, the milled pattern, for the locking bar. The combination provides enhanced key security and higher manipulation resistance. To maximize user friendliness, the key also features an elegant, ergonomic key head with a special silky texture.

The MT5+ key secure system is supported by the unique key authorization magnetic strip card. This card must be presented to the locksmith to enable additional keys to be supplied, and only when the magnetic key card is presented to the dedicated MT5+ key duplication machine can the key code be configured.

The MT5+ not only significantly upgrades security, but it also supports very large and complex master key systems, incorporating hierarchy and matrix requirements even with the same suite. The milled pattern can be used to create exclusive keyways in the marketplace.

The MT5+ is designed for high-security deadbolt systems for commercial and residential doors. The operation involves a 90° key rotation that throws the bolt 1" toward the frame, interlocking two hardened ball bearings with the strike to increase jimmying resistance. The materials used include solid brass rings and cylinder, hardened steel bolt and anti-drilling ring, steel strike, and nickel silver and stainless steel pins.

Additional features of the MT5+ include suitability for two backsets, no need for different parts, and easy conversion between standards. All Mul-t-lock items come standard with 2 keys and 1 Mul-lock key code I.D. card.
