1. 290mm Triangular Truss Geometry

Nominal truss size:

Approx. 290mm / 11.4in

The truss uses a three-chord triangular configuration.

Compared with ladder truss, the triangular geometry provides a more complete three-dimensional structure while remaining visually and physically smaller than a four-chord square truss.

This makes it useful for professional lighting and event applications where a compact truss profile is preferred.

2. 50 × 3mm Main Tubes

Main chord specification:

50mm outside diameter

3mm wall thickness

approximately:

1.97in OD × 0.12in wall

This is one of the most important specifications buyers should compare when evaluating similar 290mm truss.

Do not compare truss only by its outside sectional size.

3. Secondary Brace: 50 × 2mm

The secondary brace specification is:

50 × 2mm

This forms part of the confirmed tube configuration of this triangular truss system.

4. 20 × 2mm Diagonal Bracing

Diagonal tube specification:

20mm outside diameter

2mm wall thickness

approximately:

0.79in OD × 0.079in wall

The diagonal members connect the main chords and form the repeating triangular truss pattern.

5. 6061-T6 Aluminum Construction

The truss is manufactured from:

6061-T6 aluminum alloy

which provides the lightweight construction expected from portable professional event truss.

For rental companies, lower equipment weight can matter because the same truss is repeatedly:

loaded → transported → assembled → dismantled → stored

throughout its working life.

6. Black Finish

The black finish is especially useful where the supporting truss should visually recede into the event environment.

Typical combinations include:

Black Truss + Black Lighting Fixtures + Black Cables + Black Drapes

This can create a cleaner lighting presentation than exposed natural aluminum in dark venues.

7. Spigot / Conical Connection

Unlike the triangle bolt truss you also offer, this version uses a:

Spigot / Conical Connection System

Typical connection hardware may include:

Conical Coupler + Pin + Safety Clip

depending on the supplied package.

This makes the product clearly different from plate-ended or screw-connected triangle truss.

8. Standard Lengths from 0.5–2.5m

DragonEvent will offer standard priced options such as:

0.5m / 1.64ft

1.0m / 3.28ft

1.5m / 4.92ft

2.0m / 6.56ft

2.5m / 8.20ft

You can set these directly as SKU variants.

9. Other Custom Lengths Available

If standard modules do not create the required finished dimension, custom lengths can be manufactured.

Custom sizing is especially useful for:

• fixed venue dimensions;

• replacement sections;

• recurring rental setups;

• exhibition frames;

• lighting grids;

• matching an existing compatible truss inventory.

Compatibility Note

Do not assume every 290mm spigot triangle truss is interchangeable.

Before adding sections to an existing system, confirm:

290mm geometry + 50mm main tube + conical coupler dimensions + pin diameter + connector position

before ordering.

Stage Lighting

This is one of the primary applications.

The 290mm triangular format can be used within suitable lighting structures for:

• moving heads;

• PAR lights;

• LED fixtures;

• effect lighting;

• other compatible stage equipment.

Fixtures still require appropriate clamps and safety hardware.

For mounting and connection products, browse Truss & Rigging Accessories.

Concert Lighting

The black finish allows the truss to integrate visually with professional concert production equipment.

When positioned behind or above stage lighting, the darker structure is generally less visually dominant than natural aluminum.

For large concert systems, however, straight sections should be selected as part of the complete truss structure rather than independently.

Theatre & Studio Use

Black triangular truss is a natural fit for:

• theatres;

• studios;

• black-box venues;

• performance rooms.

The black finish helps the support structure blend into dark ceilings and backgrounds.

Club & Entertainment Lighting

For clubs and entertainment venues, the combination of:

290mm triangular geometry + black finish + modular spigot connection

works naturally with permanent or semi-permanent lighting arrangements.

DJ Event Structures

For larger mobile DJ setups, this truss can provide a more professional system than lightweight lighting stands.

Typical uses may include:

• lighting beams;

• compact goalpost frames;

• lighting surrounds;

• event backdrop structures.

For very small mobile DJ setups, however, a smaller lightweight truss may still be more practical.

Rental Company Inventory

For rental companies, several straight lengths provide greater flexibility.

A practical inventory might combine:

0.5m + 1m + 1.5m + 2m

rather than relying only on 2.5m sections.

This allows more layouts to be built from the same inventory.

How to Choose

Step 1 — Confirm You Need Spigot Truss

This product uses:

Spigot / Conical Connection

If your existing truss uses:

Bolt / Screw Connection

it is a different system.

Do not choose according to triangular shape alone.

Step 2 — Confirm the 290mm Size

Measure the actual truss section.

Nominal size:

290mm / approx. 11.4in

Then check the main tube and connector.

Step 3 — Confirm the Main Tube

Main tube:

50 × 3mm

This specification matters when:

• matching existing truss;

• choosing clamps;

• comparing alternative products.

Step 4 — Choose the Length

Start from your required finished dimension.

For example, a:

4m straight beam

could use:

2m + 2m

while a rental company may prefer:

1m + 1.5m + 1.5m

because the shorter modules can be reused for other layouts.

Step 5 — Consider Transportation

Long sections mean:

fewer connections

but also:

larger transport volume + longer packaging + more storage length.

For many rental buyers, sections between 1m and 2m provide a useful balance.

Step 6 — Use Custom Length Only Where Useful

Custom sections make sense when:

• replacing an exact existing part;

• fitting a fixed venue;

• matching an existing structure;

• building a recurring special layout.

For general rental stock, standard modular lengths normally offer greater flexibility.

Minimum Practical Package

For extending an existing compatible system:

**1 × Straight Triangle Truss Section

• Compatible Conical Couplers

• Pins

• Safety Clips**

may be enough.

For a new lighting structure, you may also need:

**+ Matching Corners

• Base / Support Components

• Fixture Clamps

• Required Safety Hardware**

Do not buy accessories before confirming actual compatibility.

Spigot Triangle Truss vs Bolt Triangle Truss

You now have both products, so these two pages should be clearly separated.

Choose This 290mm Spigot Triangle Truss When:

your existing or planned system uses:

Conical Couplers + Pins + Safety Clips

and you want:

290mm professional triangular geometry + 50×3mm main tube + fast modular connection.

Choose Triangle Bolt Truss When:

your system uses:

Bolts / Screws

for connecting straight sections.

The two systems may look similar from a distance but are not interchangeable connection systems.

Triangle Truss vs Square Truss

Choose Triangle Truss When:

you want:

three-chord geometry + smaller visual profile + professional lighting use

without the bulk of a four-chord box truss.

Choose Square Truss When:

you need:

four-chord geometry + mounting on multiple faces + a larger professional structure

or when the rest of your existing inventory already uses square truss.

Buying Mistakes to Avoid

1. Confusing Spigot with Bolt Connection

This is the most important mistake to avoid.

This product is:

Spigot / Conical Truss

not:

Bolt Truss.

2. Buying Only by “290mm”

290mm describes the nominal truss section.

Compatibility also depends on:

main tube + connector + cone + pin dimensions.

3. Assuming Every 50mm Clamp Is Suitable

A clamp may physically fit a 50mm tube, but the complete fixture mounting requirement must also be appropriate.

Select clamps according to the actual fixture and application.

4. Choosing Only 2.5m Sections

Long sections reduce joint count but may reduce rental flexibility.

A mixed inventory can be more useful.

5. Ordering Too Many Custom Sizes

Custom lengths solve specific problems.

Too many special sections can make rental inventory harder to organize.

6. Copying Load Data from Another Truss

Do not apply another manufacturer's load chart to this DragonEvent product.

Actual capacity depends on:

your manufactured truss + span + supports + connections + load position + complete configuration.

Use verified technical information for structural decisions.

7. Treating Straight Truss as a Complete Outdoor Structure

A straight truss section alone does not determine the safety of:

• outdoor roof systems;

• long spans;

• towers;

• large LED walls;

• suspended speakers;

• wind-exposed structures.

Those applications need project-specific system evaluation.
