Maximizing Safety: Essential Tips for Installing Locks on Double Doors

Double doors offer a grand entrance and increased ventilation, but they also present unique security challenges. To ensure your double doors remain a welcoming feature and not a vulnerability, proper lock installation is crucial. Here are five essential tips, each explained in detail, to maximise safety when installing locks on double doors:

1. Choosing the Right Locks for Double Doors:

Standard locks for single doors might not be suitable for double doors. For example, a standard deadbolt might only secure one door, leaving the other vulnerable. Here's what to consider when choosing locks for double doors:

• Deadbolts with Double Throws: These deadbolts extend a locking bar into both doors, providing a strong and secure connection between the two.
• Mortise Locks: These traditional locks offer a classic aesthetic and can be customised for double doors with a central strike plate that secures both doors simultaneously.
• Rim Locks: Mounted on the surface of the door, rim locks are a good option for existing doors where mortise lock installation might be difficult. Choose models specifically designed for double doors with a connecting rod to secure both sides.
• Electronic Keypad Locks: For added convenience and security, electronic keypad locks allow access via a code. These can be programmed with unique codes for different users, eliminating the need for physical keys.

2. Reinforcing the Meeting Stile:

The meeting stile is the centre post where the two doors meet. This area is often a target for break-ins because it can be a weaker point. Here's how to strengthen the meeting style:

• Strike Plate Reinforcement: Install a heavy-duty strike plate on the meeting stile where the deadbolt or mortise lock latch connects. This plate distributes the locking force across a wider area, preventing the door jamb from splitting and compromising the security of the lock.
• Security Screws: Replace standard screws with long security screws that penetrate deeper into the door frame. These offer additional resistance against forced entry attempts, making it more difficult to pry open the doors.

3. Ensuring Proper Door Alignment:

Improper door alignment can compromise the effectiveness of the locks. Here's what to do to ensure optimal functionality of the locks:

• Door Gap Consistency: The gap between the two doors should be consistent throughout the height. This allows the locks to engage properly on both sides, ensuring a secure connection.
• Vertical and Horizontal Alignment: Both doors should be plumb (vertically straight) and square (horizontally aligned) with the door frame. This ensures smooth operation of the locks and prevents binding, which can make it difficult to lock or unlock the doors.

4. Installing Additional Security Measures:

While proper locks are vital, consider layering your security with additional measures to further deter potential intruders:

• Deadbolts on Both Doors: If your chosen lock secures only one door, install a deadbolt on the inactive door as well. This provides a double layer of security, making it significantly harder for someone to break in.
• Door Reinforcements: Consider installing metal door jamb reinforcements to further strengthen the frame, especially around the lock strike plates. This creates a more robust structure that can withstand greater force.
• Security Bars: Add security bars that mount inside the door and brace against the wall or floor when engaged. These provide additional resistance against forced entry attempts, giving you valuable time to react in case of a break-in attempt.

5. Consulting a Professional Locksmith:

Installing locks on double doors can be more complex than on single doors, especially if you're unfamiliar with the process. For optimal security and peace of mind, consider consulting a professional locksmith. They can:

Assess your specific door type and needs, recommending the most suitable locks and hardware for your double doors.

Ensure proper installation of the locks, guaranteeing they function flawlessly and provide maximum security.

Offer additional security recommendations based on your specific situation, helping you create a layered security system that deters potential intruders.

By following these essential tips and considering the expertise of a professional, you can ensure your double doors add beauty and functionality to your space without compromising safety.
