Product Description

An aluminium flush bolt with rod is a specialized door locking mechanism. It is designed to secure sliding doors, double doors (such as French doors), and aluminium windows by engaging a vertical rod into the door frame.

Unlike standard surface bolts, this flush bolt is recessed into the door edge. This creates a clean, minimalist appearance while providing robust security.

The mechanism consists of a compact body and a long rod that extends into the door frame when the bolt is engaged. The flush bolt with rod is operated by a simple sliding lever that moves the bolt vertically. This makes it ideal for securing the inactive leaf of a double door setup.

What Are the Key Specifications of an Aluminium Flush Bolt?

The aluminium flush bolt with rod is engineered with precise specifications.

A typical bolt throw is 16mm to 18mm, providing a positive lock into the strike plate. The rod diameter is generally 7mm to 12mm depending on the specific model and intended door weight.

The body is commonly constructed from die-cast zinc alloy for a combination of strength and corrosion resistance. The rod is made from plated steel for high tensile strength.

The overall length varies. The standard rod measures 300mm from the body centre to the bolt tip. 600mm variants are available for taller doors.

What Materials Are Used in This Flush Bolt?

The term “aluminium flush bolt” can refer to bolts designed specifically for aluminium doors or bolts made of aluminium material.

Zinc alloy body with a steel rod is the most common construction. The body is die-cast zinc for durability, while the rod is manufactured from plated steel to provide high shear resistance.

Pure aluminium, specifically high-grade aluminium alloy, is used for the bolt body where maximum corrosion resistance and lightweight properties are required. This is typically for coastal or high-humidity environments.

What Finishes Are Available for a Flush Bolt with Rod?

The finish of a flush bolt is crucial for both aesthetic matching and corrosion resistance.

Satin chrome has a brushed, low-sheen finish that resists fingerprints. It is best for commercial offices and modern residential applications.

Anodised silver has a natural aluminium look, is durable, and corrosion-resistant. It is best for industrial settings and matching aluminium doors.

Lacquered black or white is a powder-coated or painted finish for colour matching. It is best for architectural projects and specific colour schemes.

Anodised black has a dark, sleek finish for modern aesthetics. It is best for contemporary architecture and high-end residential applications.

Dichromate plated is a corrosion-resistant finish for steel components. It is best for internal mechanisms and heavy-duty use.

How Do You Install an Aluminium Flush Bolt with Rod?

Installation of a recessed flush bolt involves fitting the mechanism into the edge of the door.

First, mortising is required. A recess is cut into the door edge to accept the flush bolt body.

Second, rod preparation is needed. The supplied rod is often threaded for part of its length. This allows the installer to trim the rod to the exact height required for the door frame.

Third, fitting the guide is essential. A rod guide is fitted inside the door frame to keep the rod aligned and ensure smooth vertical travel.

Finally, operation is simple. The bolt is engaged by sliding the lever up or down, moving the steel rod into the strike plate or keeper in the door frame.

What Are the Different Types of Flush Bolts for Aluminium Doors?

There are several configurations available.

The recessed model is designed to sit flush with the door edge, making it almost invisible when the door is closed.

The surface mount model is fixed onto the door surface rather than mortised in. This is a quicker, DIY-friendly installation option.

Offset models feature a bent rod specifically designed for windows or doors where the locking point is not directly in line with the mechanism.

Where Is an Aluminium Flush Bolt with Rod Used?

This bolt is the industry standard for several specific applications.

For double or French doors, it secures the inactive door leaf at the top and bottom. For sliding glass doors, it provides a robust locking point for aluminium sliding doors.

For aluminium casement windows, it is used to lock the handle side of the window for ventilation.

What Are the Advantages of an Aluminium Flush Bolt?

Choosing a flush bolt with rod offers several distinct advantages.

The flush design provides a clean, sleek aesthetic with no bulky protrusions. High-quality materials offer excellent corrosion resistance suitable for external exposure.

The long rod provides a high-security mechanical lock deep into the frame. Self-lubricating nylon tips ensure smooth operation without metal-on-metal grinding.

What Is Included in a Typical Flush Bolt Kit?

When you purchase a flush bolt, you will receive the flush bolt body and the steel operating lever.

You will also receive the extension rod, which is threaded for cutting to size. The kit also includes a rod guide to keep the rod straight, and the necessary mounting screws to fix the body into the door.
