Mul-T-Lock® Grade 2

Mul-T-Lock Grade Two Cronus® – High Security for the Modern LA Home

Mul-T-Lock

For Los Angeles homeowners seeking a significant and immediate upgrade to their property’s security, the conversation often begins with the deadbolt. While standard hardware from a big-box store may offer a basic locking function, it simply doesn’t provide the robust defense needed to deter a determined intruder. This is where high-security locking systems become essential.

Mul-T-Lock® Grade 2

 

Mul-T-Lock’s line of high security deadbolts has been spearheaded by the unique Cronus® Deadbolt. Utilizing superior strength and ease of installation, the Cronus® has set new standards in high-security locking, offering an ideal balance of advanced protection, modern aesthetics, and practical value. Constructed of solid brass and hardened steel, the Cronus® deadbolt is recognized by many as the best deadbolt in its class.

At Guardian Angel Locksmith, we recommend the Cronus® for clients who want to move beyond basic security into a truly protected space. Let’s explore the features that make this ANSI Grade 2 deadbolt a formidable barrier for your home.

 

Decoding the Cronus®: Features That Define Its Strength

 

The Cronus® is engineered from the ground up to resist common methods of forced entry, incorporating layers of protection that work in concert to secure your door.

 

Understanding ANSI Grade 2 Security

 

While the ANSI Grade 1 rating (found on the Hercular®) represents the highest level of security, the ANSI Grade 2 rating of the Cronus® is a commercial-grade certification that is vastly superior to the standard Grade 3 hardware found on most homes. A Grade 2 lock is tested to withstand substantial force and must endure 150,000 opening and closing cycles—more than enough for a lifetime of residential use. For most homes in Los Angeles, upgrading to a Grade 2 deadbolt like the Cronus® is the single most effective step you can take to harden your entryway.

 

The Armored Core: Cylinder Protector and Steel Rosettes

 

The most vulnerable part of a standard deadbolt is the cylinder housing. The Cronus® addresses this weakness directly with a robust cylinder protector. This visible, hardened steel ring surrounds the lock cylinder, shielding it from attacks like pipe wrenches or pliers that attempt to twist the cylinder out of the door. This is further reinforced by steel core rosettes, which provide a powerful internal structure beneath the stylish brass exterior, preventing the lock from being pried or hammered off the door.

 

The Unyielding Bolt: 1-Inch Throw with Hardened Steel Insert

A deadbolt is only effective if its bolt can fully and securely engage with the door frame. The Cronus® features a full 1-inch (25 mm) bolt throw, extending deep into the frame for maximum resistance to kick-ins and prying. Inside this bolt is a hardened steel insert, a critical feature that allows the bolt to spin freely if a burglar attempts to cut through it with a hacksaw, rendering the attack ineffective.

Versatility and Precision: The Adjustable Backset

A secure fit is critical for a lock’s performance. The Cronus® features an adjustable backset for either (60 mm) or (70 mm) configurations. This versatility ensures a perfect fit for nearly all standard residential doors in the United States, eliminating the dangerous gaps and misalignments that can compromise a poorly fitted lock.

Choosing the Right Cronus® Configuration

Like all of Mul-T-Lock’s deadbolts, the Cronus® is available in two configurations to suit your specific door and security needs.

1. Mul-T-Lock® Grade 2 SINGLE-SIDED DEADBOLT

This is the standard and most popular choice for residential applications. It features a keyway on the exterior and an ergonomic thumb-turn on the interior for convenient, key-free locking and unlocking from the inside.

FEATURES:

  • Single cylinder (with thumb-turn)
  • Robust cylinder protector
  • Steel core rosettes
  • Stylish design
  • Allows for precise, professional installation

SPECIFICATIONS:

  • Locking bolt reinforced with hardened steel insert
  • Full 1” (25 mm) bolt throw
  • Adjustable backset: (60 mm) or (70 mm)
  • Door thickness: (35 mm) to (45 mm)

2. Mul-T-Lock® Grade 2 DOUBLE-SIDED DEADBOLT

This model requires a key on both the inside and the outside. It is the ideal choice for doors with glass panels or any door where an intruder could potentially break the glass and reach inside to unlock the door.

IMPORTANT SAFETY NOTICE: We at Guardian Angel Locksmith strongly advise our clients to consider the safety implications of a double-sided deadbolt. In the event of a fire or other emergency, it may delay your exit. It is crucial to always have a key accessible near the door for egress. Please consult your local fire safety codes before installation.

  • Double cylinder
  • Robust cylinder protector
  • Steel core rosettes
  • Stylish design
  • Allows for precise, professional installation

The Mul-T-Lock Ecosystem: Patented Key Control

 

One of the most important features of any Mul-T-Lock product is the strict key control that comes standard. All Mul-T-Lock cylinders are provided with a unique Key Order Card. This card contains the specific authorization needed to duplicate your keys and must be presented to a certified Mul-T-Lock dealer to do so. This system prevents anyone—from a temporary contractor to a valet—from making an unauthorized copy of your key, giving you complete control over who can access your property.

 

Security in Style: Finishes to Match Your Home

 

The Cronus® deadbolt proves that you don’t have to compromise on style to get high security. Its sleek, stylish design is available in a wide range of finishes to perfectly match your home’s aesthetic and existing hardware:
