F44 400x400mm Standard Sleeve Block Connecting F34 & F44 Square Box Truss

The Truss Ground Support Sleeve Block is specifically crafted for the F44 Series 400mm Trussing and boasts 4 connecting sides. Our F44 Truss is renowned as the most reliable staging support system in the industry, designed to meet the highest standards of safety and performance. With its ability to support various structures, it provides great convenience in construction and can function as a four-way angle block for trusses of varying sizes.

This corner block/sleeve block is primarily used in conjunction with 400mm ground support tower truss and offers a sturdy yet lightweight trussing solution, making it ideal for mobile DJs, bands, outdoor performances, nightclubs, live mobile productions, or permanent installations.

Product Information

Product Description

The DragonStage F44 400x400mm Ground Support Sleeve Block is designed as the main connection node between the vertical tower and horizontal beam trusses in a ground-support truss system.

This model uses a 400x400mm sleeve-block body with four connection faces and is configured to work with compatible F34 approx. 290mm truss and F44 400mm truss arrangements.

Instead of being only a fixed corner connector, the sleeve block is used as part of the tower system, providing connection positions around the vertical support for the main horizontal truss beams.

For customers building or replacing components in a complete tower system, see our Tower Elements range.

For other matching aluminum truss sizes and configurations, see Aluminum Truss.

What Does the Sleeve Block Do?

In a ground-support truss system, the sleeve block creates the junction between:

vertical tower + horizontal beam truss

Its four-sided configuration allows horizontal truss members to be connected from different directions according to the system layout.

Typical applications include:

• Roof truss towers

• Lighting grids

• LED screen support structures

• Ground-support truss systems

• Concert and event truss structures

For complete LED support configurations, you can also view LED Ground Support Truss.

F34 and F44 Connection

One useful feature of this sleeve block is that it can be configured to connect different truss sizes within the same support system.

For this product:

• F44: approximately 400x400mm square truss

• F34: approximately 290mm square truss

This is useful when the project uses a larger F44 beam together with a smaller F34 tower or secondary truss component.

However, F34 and F44 are not automatically universal across every manufacturer's truss. Connector position, tube spacing, spigot specification, and actual outside dimensions should be checked before ordering.

Four-Side Connection

The sleeve block provides four connecting sides, allowing the same central component to be used for different beam directions.

Depending on the truss system, this can support layouts such as:

• straight beam connection

• two-direction beam connection

• three-direction connection

• four-direction truss grid connection

The unused connection faces can remain available for future system expansion or another project configuration.

For related connectors and tower hardware, see Truss System Accessories.

Typical Applications

• Aluminum roof truss systems

• Ground-support lighting truss

• LED screen support structures

• Concert truss systems

• Exhibition truss structures

• Touring production systems

• Replacement or expansion of existing tower systems

Before Ordering: Compatibility Matters

A sleeve block should not be selected only by the words “F34” or “F44”.

Before production, please confirm:

• Truss outside dimensions

• Tower truss size

• Beam truss size

• Connector type

• Main tube spacing

• Existing sleeve-block dimensions, if replacing one

• Photos or drawings of your current truss system

If you already have existing truss from another supplier, sending us clear photos plus exact measurements is safer than ordering only by model name.

Important Technical Note

The current product information confirms the F44 400x400mm sleeve-block format, four connecting sides, and F34/F44 compatibility configuration. The existing page does not provide a verified allowable load, lifting capacity, safety factor, or engineering calculation for this individual component. Dragon Stage

For this reason, the sleeve block should be treated as one component of the complete tower system, not as an independent indication of the allowable load of the entire truss structure.

FAQ

What is an F44 sleeve block used for?
It is used as the connection node between a ground-support tower and the horizontal truss beams around it.

What size is this sleeve block?
This model is an F44 400x400mm sleeve block.

Can it connect both F34 and F44 truss?
Yes. This version is configured for compatible F34 approx. 290mm and F44 400mm square truss connections.

Does it have connections on all four sides?
Yes. The sleeve block provides four connecting faces for different truss directions.

Is this the same as a normal corner block?
Not exactly. A corner block is mainly a fixed geometry connector. This product is primarily a tower sleeve block used within a ground-support system, although its multiple connection faces perform a similar beam-connection function.

Is it compatible with any F34 or F44 truss from another manufacturer?
Not automatically. Different manufacturers may use different tube spacing, connector dimensions, or connection geometry. Please confirm dimensions before ordering.

Can I use it to replace an existing sleeve block?
Yes, but please provide the existing sleeve-block dimensions, truss dimensions, connector details, and photos so compatibility can be checked first.

What information should I send for quotation?
Please send your tower-truss size, beam-truss size, F34/F44 configuration, connector type, quantity, and photos or drawings of the existing system.

Why Choose DragonStage

DragonStage supplies complete Aluminum Truss systems as well as individual tower elements and replacement components.

For sleeve-block inquiries, our focus is not only the nominal product name. We can check the actual connection relationship between your tower and beam truss before production, which is particularly useful when expanding or repairing an existing truss inventory.
