Understanding Flush Bolts for Double Doors A Key Component in Door Hardware

When it comes to the functionality and security of double doors, flush bolts play a crucial role. These specialized hardware pieces not only offer enhanced locking mechanisms but also contribute to the aesthetic appeal of a double door system. This article will explore the significance of flush bolts, the different types available, and the leading companies that manufacture these essential components.

What are Flush Bolts?

Flush bolts are vertical locking devices installed into the edge of a double door. They are typically used in configurations where one door is active (the primary door used for entry and exit), while the other door remains inactive or stationary. When closed, the inactive door can be securely locked in place, preventing it from being ajar or easily opened. This security feature is particularly important in commercial settings, such as offices, storefronts, and public buildings, where unauthorized access needs to be minimized.

How Flush Bolts Work

Flush bolts operate by extending a metal bolt into the floor or the head of the door frame. When the inactive door is closed, the flush bolt can be engaged, securing the door and making it impossible to open without unlocking the bolt first. Many modern flush bolts feature a simple thumb turn mechanism, making them easy to operate. Some advanced models may integrate electronic locking systems for enhanced security.

Types of Flush Bolts

Flush bolts come in various designs to accommodate different types of doors and security needs. The most common types include

1. Vertical Flush Bolts A standard option with a single metal bolt that extends vertically into the frame or floor. 2. Horizontal Flush Bolts These bolts extend horizontally and are typically used in specific situations, such as when a bolt needs to secure a door against lateral movement.

3. Concealed Flush Bolts Designed to be hidden within the door, these bolts provide a seamless look while maintaining security.

4. Electric Flush Bolts Incorporating electronic mechanisms, these bolts can be operated remotely or via access control systems, making them suitable for high-security environments.

Selecting the Right Flush Bolts

When choosing flush bolts for double doors, several factors should be considered

- Material Flush bolts are commonly made from stainless steel, brass, or aluminum. The choice of material will affect both durability and aesthetics. - Size The dimensions of the flush bolt must match the door’s thickness and the specific installation requirements.

- Security Rating Opt for flush bolts with a high security rating, especially if the doors are installed in vulnerable areas.

- Ease of Use Ensure the locking mechanism is user-friendly, allowing for quick exit and entry.
