Engineered for Secure Container Stacking and Fixing
The Dovetail Twistlock Stacking Pin from Quickfit Container Accessories is a trusted, industry-standard component for securing containers safely and efficiently. Designed to interlock containers vertically or anchor them to a fixed base, each dovetail twistlock provides the strength and precision required to maintain stability during transport, loading, and long-term storage.
Whether you operate a busy port, logistics yard, or construction site, this twistlock dovetail ensures your containers remain firmly in position, preventing movement caused by vibration, wind, or uneven terrain. Manufactured to meet global shipping standards, it offers peace of mind when working with heavy loads or multi-stack configurations.
Built for Performance in Harsh Conditions
Every container dovetail twistlock in our range is crafted from high-strength cast and forged steel, delivering the toughness needed for demanding industrial use. Finished with a hot-dip galvanised coating, it resists corrosion, rust, and wear — even in marine or coastal conditions. This means you can rely on consistent performance year after year, regardless of climate or workload.
The low-profile base design ensures a stable, precise fit between containers, maintaining alignment and reducing strain on locking mechanisms. Tested to a tension rating of 500 kN, this dovetail container securing twistlock can safely withstand the immense forces generated during lifting, stacking, and transit. Its robust construction makes it ideal for high-frequency applications where safety and reliability cannot be compromised.
Flexible Solutions for Temporary and Permanent Fixings
The Quickfit dovetail twistlock system is compatible with both Dovetail Foundations and Twistlock Fixing Plates, giving you the flexibility to choose between temporary or permanent anchoring solutions.
When paired with a Dovetail Foundation, the twistlock slides easily in and out of the base plate, offering a secure yet removable fixing — perfect for operations where container layouts change frequently. This setup allows for quick deployment and reconfiguration without the need for welding or complex tools.
For permanent installations, the Twistlock Fixing Plate provides a combined solution where the twistlock dovetail can be bolted or welded to the ground. This method offers maximum stability for long-term stacking or site-based conversions, such as modular offices, workshops, or containerised storage units.
Both systems share the same precision dovetail base, ensuring optimal alignment and locking accuracy while maintaining interchangeability across your fleet or site setup.
