Dragonstage Aluminum Spigot 400x400mm / 389x389mm Square Box 6 Ways Corner Truss Cube Connector

he DragonStage CS40BOX is a 6-way aluminum spigot truss cube connector for compatible 400mm-class square box truss systems. The product is commonly described as a 400x400mm truss cube, while the current product page also identifies the corresponding size as 389x389mm. Its six connection directions allow compatible truss sections to be connected from the front, rear, left, right, top, or bottom according to the required frame configuration. 

Product Information

The current product page identifies the connector as model CS40BOX and describes it as a 400x400mm / 389x389mm square box 6-way corner truss cube connector. Dragon Stage

Product Description

The DragonStage 400mm / 389mm Aluminum Spigot Truss 6-Way Cube Connector is a modular junction component used when several square truss sections need to meet at one structural point.

Unlike a simple fixed 90-degree corner, a 6-way cube provides connection positions around multiple faces of the block. This allows the same connector to be used in a wider range of layouts such as:

• L-shaped corners

• T-junctions

• cross connections

• vertical-to-horizontal transitions

• multi-direction exhibition frames

• lighting grids

• stage truss structures

For other connection components, see Typical Truss Corner Connector.

If you are building the complete system from standard straight sections, see Standard Spigot Truss.

What Does “6-Way” Mean?

“6-way” refers to the potential connection directions around the cube:

• left

• right

• front

• rear

• top

• bottom

This does not mean every project must use all six directions at the same time.

For example, the same cube may be used as:

• a 2-way corner

• a 3-way junction

• a 4-way intersection

• a vertical tower-to-beam connection

• part of a larger six-direction truss grid

The actual connection arrangement depends on the project layout and the compatible connector hardware installed on the cube.

For general principles about how truss geometry changes with system layout, see Truss Design & Configuration.

400mm vs 389mm — Why Are Both Numbers Used?

This product is commercially listed as a 400mm square truss connector, while the current product title also gives 389x389mm. Dragon Stage

In practice, “400mm” can function as the nominal series name, while the actual measured outside dimension of the matching truss system may be different.

For this reason, when buying a replacement cube or connecting it to truss from another supplier, do not rely only on the word “400mm”.

Please confirm the actual:

• outside truss size

• chord center spacing

• spigot position

• connector dimensions

• pin-hole position

• existing cube dimensions

That is especially important when the customer already owns truss from another factory.

Main Advantages

• One cube can support several connection directions

• Useful for modular and reusable truss systems

• Suitable for building corners and intersections

• Helps reduce the need for many fixed-angle corner pieces

• Can be used in both horizontal and vertical layouts

• Practical for rental companies with changing event configurations

• Compatible system can be expanded later with additional truss sections

For more compatible components, see Truss Accessories.

Typical Applications

This 6-way cube connector can be used in:

• lighting truss grids

• stage truss structures

• exhibition booths

• trade-show frames

• event entrances

• display structures

• DJ truss systems

• temporary event frameworks

• multi-direction aluminum truss assemblies

For other aluminum truss sizes and systems, see Aluminum Truss.

Is a 6-Way Cube Better Than a Fixed Corner?

Not necessarily. They solve different problems.

A fixed corner is simple when the required angle and direction are already known.

A 6-way cube is more useful when:

• the same inventory needs to create different structures

• several truss directions meet at one point

• vertical and horizontal trusses need to connect together

• the customer wants more flexibility for future layouts

So the main advantage is configuration flexibility, not that the cube is automatically stronger than every fixed corner.

Compatibility Is More Important Than the Product Name

A common purchasing mistake is assuming:

“Both products say 400mm, so they must fit.”

That is not always true.

Two truss systems can both be sold as 400mm square truss while having different:

• actual outside dimensions

• chord spacing

• connector positions

• spigot dimensions

• pin geometry

If you are buying this cube to expand or repair an existing structure, please send us the real measurements and connection photos before production.

Before Ordering

Please provide:

• existing truss outside dimensions

• main chord spacing

• connector type

• spigot dimensions

• required connection directions

• quantity

• photos of your existing truss if matching old inventory

For a completely new system, simply tell us the intended truss layout and overall structure dimensions.

Important Technical Note

The current product page confirms the CS40BOX model, 400x400mm / 389x389mm description, aluminum spigot configuration, and six-way connector concept, but it does not publish a verified allowable load for this cube as an independent structural component. Dragon Stage

The load capacity of the complete structure depends on:

• connected truss type

• span

• orientation

• support arrangement

• connection configuration

• applied loads

• complete structural system

Therefore, the six-way cube should not be treated as an independent proof of the load capacity of the finished truss structure.

FAQ

What is this product?
It is an aluminum 6-way cube connector used to connect compatible square spigot truss sections in multiple directions.

What is the model?
The current product model is CS40BOX. Dragon Stage

Is it 400x400mm or 389x389mm?
The current page uses both descriptions: 400x400mm as the nominal product series and 389x389mm in the product naming. For replacement orders, actual dimensions should be confirmed before production. Dragon Stage

What does 6-way mean?
It means the cube can provide connection positions in up to six directions: front, rear, left, right, top, and bottom.

Do I have to use all six connections?
No. Only the directions required by the final truss layout need to be used.

Can this replace a normal corner truss?
In some modular layouts, yes. A six-way cube can form several corner and junction configurations, but the final geometry still depends on the system.

Can it connect to another manufacturer's 400mm truss?
Possibly, but not automatically. The actual dimensions, connector positions, and spigot geometry must be checked.

Are the half connectors and pins included?
The current page does not clearly specify the exact connector package included with every order, so this should be confirmed in the quotation rather than assumed. Dragon Stage

Can it be used vertically?
Yes, compatible cube systems can be used where horizontal and vertical truss members meet, provided the complete structure is designed accordingly.

What information do you need for quotation?
Please send the truss size, connection directions required, quantity, and photos or drawings if you need compatibility with existing equipment.

Why Choose DragonStage

DragonStage supplies both complete Aluminum Truss systems and individual connectors for expansion, replacement, and custom configurations.

For cube connectors, our recommendation is simple: match the real geometry first, not only the model name.

This is particularly important for customers who already own truss and want to add new corners, towers, grids, or exhibition frames.
