Main Specifications

Multi-Level Ringlock FOH Main Structure

The main body of this product is built from a modular Ringlock structure.

Compared with a simple FOH booth, this configuration provides a vertical multi-level working structure, suitable for event-control functions where operators require a more elevated position and a more organized technical working space.

According to the supplied BOQ, the main Ringlock structure includes:

• Main vertical standards

• Horizontal ledgers

• Diagonal braces

• Single-row 2m structural members

• Platform planks

• Ladder-access components

Because the tower is based on modular Ringlock components, it can be transported, assembled, dismantled, and reused across different event projects.

For related Ringlock systems, see our Ringlock Stage System and Steel Ringlock Stage Platform.

Hybrid Aluminum Roof Frame

One of the key differences of this FOH product is that it is not a full Ringlock-only roof solution.

Instead, the roof is formed using a dedicated aluminum frame package, creating a hybrid Ringlock + aluminum structure.

The supplied BOQ includes:

• Aluminum roof beams – 6.1231m × 6 pcs

• Side-wall aluminum tarpaulin posts – 6.0000m × 9 pcs

• Aluminum column forks – 0.5000m × 9 pcs

• Outrigger canopy beams – 1.5000m × 9 pcs

This aluminum roof frame works together with the Ringlock tower body to support the sloped roof and enclosure system.

For more aluminum structural products, customers can also browse our Aluminum Truss and Stage Truss ranges.

Sloped Roof Configuration

The roof form is one of the defining features of this tower.

The confirmed dimensions indicate:

• Roof high point: 7m

• Roof low point: 6m

• Side height: 6m

This creates a single-slope roof profile, which is different from a flat control platform or a small pitched booth roof.

The current product page records the geometry only. It does not make a separate engineering claim regarding drainage performance, wind management, or roof loading.

Enclosed FOH Working Space

This FOH tower includes a fabric covering and enclosure package.

According to the BOQ, the supplied fabric components include:

• Main roof tarpaulin – 48.0000m² × 1 pc

• Outrigger canopy tarpaulin – 3.0000m² × 6 pcs

• Curtain 1 (side) – 24.0000m² × 2 pcs

• Curtain 2 (front/back) – 24.0000m² × 1 pc

These components help form a more protected technical operating area compared with a fully open scaffold tower.

The exact opening direction, viewing side, and curtain arrangement can be adjusted according to the actual FOH layout.

Platform and Access Components

The tower includes working platforms and access components for internal circulation and operation.

The BOQ includes:

• Platform planks – 0.2780m × 84 pcs

• Open platform plank, aluminum + wood – 2.0000m × 2 pcs

• Heavy-duty aluminum ladders – 2 pcs

These components suggest a multi-level operator tower where internal access and working platform continuity are required.

This makes the structure suitable for technical applications such as:

• Audio control

• Lighting control

• Video control

• Show calling

• Event management

• Production coordination

For broader event applications, see our Concert Event page.

Lower Auxiliary Base Structure

The BOQ also includes a separate lower base structure package:

• Base vertical standards – 1.0000m × 6 pcs

• Base ledgers – 2.0000m × 10 pcs

• Base diagonal braces – 2.8300m × 12 pcs

• Base planks – 2.0000m × 12 pcs

This indicates that the tower is supplied not only as a vertical FOH body, but also with an auxiliary lower structural package used as part of the complete project configuration.

In addition, the BOQ includes:

• 50×2mm ballast steel pipe + accessories – 4.0000m × 2 pcs

This should be recorded as part of the supplied product package, but it should not be presented as a universal or verified ballast solution for all installations.

Typical Applications

This type of multi-level hybrid FOH control tower is suitable for:

• Concert FOH control

• Festival operator towers

• Audio and lighting control positions

• Video and media control

• Technical production platforms

• Temporary event command positions

• Elevated control structures for outdoor events

The 4m × 4m footprint makes it compact enough for many event sites, while the 7m height provides an elevated control position compared with a simple ground-level FOH enclosure.

Complete Product Package

This is not just a scaffold tower and not just a small roof frame.

The product package combines:

Ringlock tower structure
+
multi-level working platforms
+
ladder access
+
aluminum roof frame
+
roof tarpaulin
+
side and front/rear curtains
+
auxiliary lower structure
+
ballast-related steel pipe components

This is why it fits well on dragontruss.com as a DragonStage hybrid FOH product rather than being treated as a single-material scaffold item.

Custom Manufacturing Options

The 4m × 4m × 7m configuration shown here is one custom project layout.

DragonStage can customize:

• Tower width

• Tower depth

• Overall tower height

• Roof low / high points

• Number of working levels

• Platform configuration

• Ladder or stair access

• Curtain layout

• Roof-cover design

• Open or enclosed sides

• Auxiliary base structure

• Equipment access openings

• Cable routing positions

For non-standard event structures, see our Custom Stage Production service.

What Information Is Needed for Quotation?

For a similar hybrid FOH tower, customers should provide:

• Required width and depth

• Required total height

• Number of working levels

• Required operator capacity

• Equipment to be placed on each level

• Indoor or outdoor use

• Open or enclosed side requirements

• Roof-cover requirements

• Access type

• Installation location

• Ground condition

• Required usage period

• Existing drawings or reference images

If the project is for outdoor use, the site condition and project-specific stabilization requirements must also be confirmed before the final configuration is approved.

Important Technical Note

The dimensions and BOQ on this page describe the confirmed product configuration provided for this FOH tower.

They do not establish:

• Working-platform load capacity

• Roof load capacity

• Wind resistance

• Ballast requirement

• Anchoring requirement

• Safety factor

• Structural certification

• Engineering approval

• Local compliance approval

The BOQ includes ballast-pipe components, but no verified project-specific ballast calculation has been provided. For that reason, this page records the product configuration only and does not convert it into a universal engineering conclusion.

FAQ

What is the size of this FOH control tower?

The tower measures approximately 4m wide × 4m deep, with a maximum structure height of approximately 7m.

Is this a booth or a tower?

This product is better described as a multi-level FOH control tower, because it provides elevated multi-level working space rather than only a ground-level booth.

What kind of roof does it use?

It uses a sloped hybrid roof system with a high point at approximately 7m and a low point at approximately 6m.

Is the main structure all aluminum?

No. This is a hybrid product. The main structural body uses Ringlock components, while the roof system uses aluminum framing components.

Are the curtains included?

Yes. According to the supplied BOQ, the structure includes side curtains, front/rear curtain panels, and roof tarpaulin components.

Is access included?

Yes. The BOQ includes heavy-duty aluminum ladders and open platform components for access within the structure.

Can the size be customized?

Yes. Width, depth, height, number of levels, roof geometry, curtain arrangement, and access type can all be customized.

Is ballast included?

The BOQ includes two 4m-long 50×2mm ballast steel pipes with accessories. However, the actual ballast requirement must still be confirmed according to the installation conditions.
