Mul-t-lock Hercular Single Cylinder Deadbolt with Decorative Rosette and Thumb Turn - Antique Brass

The Mul-t-lock High Security Deadbolt System is designed for both commercial and residential door applications, offering enhanced security features. The key operation involves a 90-degree rotation, which throws the hardened steel bolt 1 inch towards the frame, interlocking two hardened ball bearings with the strike plate to increase resistance against jimmying attempts.

The materials used in the construction of this deadbolt system are of the highest quality. The rings and cylinder are made of solid brass, while the bolt and anti-drilling ring are crafted from hardened steel. The strike plate is also made of steel, and the pins are composed of nickel silver and stainless steel.

One of the notable features of the Mul-t-lock Deadbolt System is its versatility. It is suitable for two different backsets, eliminating the need for different parts. Moreover, the system allows for easy conversion between standard and drive-in installations, providing users with a convenient solution.

The deadbolt is supplied with a standard 1-inch throw, ensuring a secure fit within the door frame. Additionally, the thumbturn tail is self-adjustable to accommodate various door thicknesses, adding to the system's adaptability.

At the heart of the Mul-t-lock Deadbolt System lies the unique, high-precision telescopic pin tumbler mechanism. This mechanism is designed to be pick and drill resistant, making it highly secure and suitable for applications with high-security requirements.

The Mul-t-lock Deadbolt System is UL437 listed for burglary resistance and UL fire-rated, meeting the stringent ANSI Grade 1 standards. This certification ensures that the system provides exceptional security and reliable performance in both residential and commercial settings.

Each Mul-t-lock item comes standard with two keys and a Mul-lock key code identification card, allowing users to easily manage and duplicate keys as needed.

In conclusion, the Mul-t-lock High Security Deadbolt System is a comprehensive security solution that combines advanced features, robust construction, and compliance with industry-leading standards.
