Types of Stainless Steel Door Locks

1. Deadbolts:

   • Single Cylinder: Keyed outside, thumb turn inside.
   • Double Cylinder: Keyed on both sides, enhancing security.

2. Knob Locks: Often used on interior doors; less secure than deadbolts.

3. Lever Locks: Common in commercial settings, easy to operate.

4. Smart Locks: High-tech options featuring keypads, Bluetooth, or biometric access.

1. Types of Deadbolts

1. Single Cylinder Deadbolt:

   • Operation: Keyed on the outside and has a thumb turn on the inside.
   • Use: Commonly used on entry doors; easy to operate but may not be suitable for doors with glass panels nearby, as the thumb turn can be accessed from outside.

2. Double Cylinder Deadbolt:

   • Operation: Keyed on both the outside and inside.
   • Use: Provides extra security, especially for doors with nearby glass, as it prevents unauthorized access through broken glass. However, it can pose a safety risk in emergencies since both sides require a key to unlock.

3. Vertical Deadbolt:

   • Operation: Bolts slide vertically into the door frame.
   • Use: Offers added security, often used in high-risk areas. It can be more complex to install.

4. Smart Deadbolt:

   • Operation: Uses electronic mechanisms, can be controlled via smartphones, keypads, or biometric systems.
   • Use: Allows for keyless entry and remote access, enhancing convenience and security.

Features

• Material: Typically made from steel or brass, providing strength and resistance to tampering.
• Security Ratings: Look for ANSI/BHMA grading (Grade 1 being the highest), which indicates resistance to forced entry.
• Installation: Most require a standard door preparation but may need professional installation for optimal security.
• Key Control: Some models offer key control systems, which prevent unauthorized duplication of keys.

Advantages

• Increased Security: Deadbolts provide a higher level of security than standard knob locks.
• Durability: They are designed to withstand physical attacks and harsh weather conditions.
• Versatility: Available in various styles and finishes to match different door aesthetics.

Maintenance

• Regular Checks: Ensure the lock functions smoothly; lubricate with a silicone-based lubricant as needed.
• Key Replacement: If keys are lost, consider rekeying or replacing the lock for security.

2. Types of Knob Locks

1. Single Cylinder Knob Lock:

   • Operation: Keyed on the outside and has a thumb turn on the inside.
   • Use: Commonly used for residential entry doors but less secure than deadbolts.

2. Double Cylinder Knob Lock:

   • Operation: Keyed on both the outside and inside.
   • Use: Offers enhanced security, especially on doors with glass nearby, but may pose safety risks in emergencies since it requires a key to unlock from the inside.

3. Keyless Knob Locks:

   • Operation: Operated through keypads or smart technology without a physical key.
   • Use: Convenient for homes and businesses, allowing for keyless entry.

Features

• Material: Commonly made from materials like brass, stainless steel, or zinc, providing varying levels of strength and durability.
• Security Ratings: Look for ANSI/BHMA ratings; higher grades indicate better resistance to tampering.
• Design Variations: Available in various styles and finishes to match different door designs.

Advantages

• Ease of Use: Simple to operate; turning the knob allows for quick access.
• Cost-Effective: Generally less expensive than deadbolts, making them a budget-friendly option for many applications.
• Versatile: Suitable for both interior and exterior doors.

Installation and Maintenance

• Maintenance: Regularly check for smooth operation and lubricate the mechanism as needed to prevent sticking.

3. Types of Lever Locks

1. Single Cylinder Lever Lock:

   • Operation: Keyed on the outside with a lever handle on the inside.
   • Use: Common for entry doors, allowing easy access from the inside without a key.

2. Double Cylinder Lever Lock:

   • Operation: Keyed on both sides, requiring a key to unlock from either side.
   • Use: Provides added security, especially for doors near glass, but can be a safety concern in emergencies.

3. Keyless Lever Lock:

   • Operation: Uses keypads or electronic access, allowing keyless entry.
   • Use: Ideal for homes and businesses seeking convenience and enhanced security.

Features

• Material: Typically made from durable materials like stainless steel or brass, offering good resistance to wear and tear.
• Security Ratings: Check for ANSI/BHMA ratings to determine the level of security; higher grades indicate better performance against forced entry.
• Accessibility: The lever design is easier to operate than knobs, making it accessible for people of all ages and abilities.

Advantages

• Ease of Use: The lever handle makes it simple to open, especially in high-traffic areas.
• Versatility: Suitable for a wide range of applications, including commercial buildings, offices, and residential homes.
