Side-to-side connection of sea containers is possible with the steel Bridge Fittings. Thanks to the adjustable system (with threaded rod), two containers can be securely connected. The threaded section of the bridge fitting can be tightened using a wrench 32 or an adjustable wrench (Bahco). Bridge Fittings are available in two lengths: the small variant is a maximum of 260 mm wide and the larger version has a maximum width of 330 mm. The Bridge Fittings are manufactured from high-quality galvanized steel, making them suitable for many years of intensive use. The exact dimensions of the Bridge Fitting can be found in the technical drawing.
The Bridge Fittings are specifically designed to secure containers side by side. Thanks to the adjustable system, two containers can be clamped together easily. Both ends of the fitting are placed into the corner castings of the containers. These corner castings feature a special opening on the side, into which the Bridge Fittings can be clamped. Bridge Fittings are mainly used to secure containers on board. In addition, containers on land can also be secured using the fittings. Besides securing containers, various custom constructions and portacabins can also be safely anchored through Bridge Fittings, provided they are equipped with ISO Corner Castings. For vertical stacking of containers or constructions, other securing products are suitable. Examples include the Intermediate Twistlock IF-51 and the Depot Stacker, which are ideal for vertical container locking.
The Bridge Fittings from Navacqs are highly versatile. The distance between two containers or constructions is not always equal. The intelligent design allows you to adjust the fitting to match the spacing. The fitting consists of two steel claws connected by a pin. The pin is fitted with a threaded rod. Tightening the rod allows the claws to be drawn toward each other, clamping the containers. The threaded rod can be tightened using wrench 32 or an adjustable wrench (Bahco).
The small version, 260 mm and 330 mm, refers to the spacing between the container walls. In situations where the containers are placed tightly together, the 260 mm version is suitable. The larger 330 mm variant offers more flexibility and a wider range of container spacing. Both variants clamp the containers securely for safe operations.
The Bridge Fittings are made from high-quality galvanized steel, which protects them from weather conditions and seawater. The protective coating prevents corrosion and ensures the fittings can be used for long periods. For smooth operation and long service life, it is recommended to lubricate the fittings regularly. This prevents dirt from entering the threaded rod and provides extra protection against all weather conditions.
The exact dimensions of the Bridge Fitting can be found in the technical (.pdf) drawing. A drawing is available for the “Small” (260 mm) version and the “Large” (330 mm) version. A 3D drawing is also available as a .stp file. This allows the Bridge Fittings to be integrated into a technical design package for custom-built constructions.

A bridgefitting is an adjustable coupling used to secure two containers to each other side by side. The fitting is placed in the openings of the corner castings and then tightened, so the containers are clamped firmly against each other.
Bridgefittings are used when containers stand next to each other and mustn't shift, for example on a ship or storage yard.
They provide a stable arrangement without the containers needing to be welded together.
Containers are coupled side by side by placing a bridgefitting into the corner castings of both containers. Tightening the thread pulls the two ends toward each other and clamps the containers together.
This is done with a wrench or adjustable spanner.
In practice:
place the ends in both containers
tighten the fitting
the containers are pulled tightly against each other
This means they can no longer shift apart.
Bridgefittings are used when containers are placed next to each other and extra stability is needed.
You see this, for example, with:
container arrangements on ship decks
temporary storage at terminals
coupled units such as portable cabins
Without coupling, containers can drift apart due to movement or wind. With bridgefittings, they stay neatly together.
A bridgefitting couples containers horizontally (side by side), while a twistlock locks containers vertically (on top of each other).
Brief difference:
bridgefitting → coupling side by side
twistlock → stacking and locking
Both systems are often used together in container arrangements.
The right size depends on the distance between the containers. Bridgefittings are adjustable, but have a maximum span.
In practice:
small variant → containers stand close together
larger variant → more space between containers
The fitting is adjusted to size by tightening the thread until the containers are held firmly in place.
Yes, bridgefittings can also be used for structures fitted with container corner castings. Think of steel frames or temporary units.
Because they use standard ISO corner castings, they can make the same connection as with containers.
This makes them suitable for:
modular building systems
temporary installations
custom constructions
