12-Degree Corner Overview

A Fixed 2-Way Corner for a Planned Truss Directional Change.

The EVT290X-12DA Black is a fixed 2-way, 12-degree corner for compatible 290 mm square aluminum truss layouts. It changes the direction of one truss run by a fixed 12 degrees. It is not a variable-angle corner, a multi-way junction, a straight truss section, or a universal truss connector.

Fixed 12-Degree Angle
Provides a fixed 12-degree change in direction for a planned truss layout.
Two Connection Directions
Connects two compatible truss sections in the specified fixed-angle configuration.
Fixed Configuration
The corner angle is fixed. Use this component only where the project drawing calls for a 12-degree directional change.
Matte Black Finish
The matte black powder-coat finish is suited to visible truss layouts where the structure should visually recede.

What Does a 12-Degree Corner Connect?

Two Compatible Truss Runs at a Fixed 12-Degree Change.

The EVT290X-12DA Black connects two compatible truss directions. The corner establishes a fixed 12-degree directional change between the mating truss runs. In a complete planned configuration, that angle can be used as a fixed-angle section within a sloped roof or canopy layout.

First Truss Direction
Use one receiver direction to connect the first compatible truss run specified by the project drawing.
Second Truss Direction
Use the second receiver direction to continue the truss line at the fixed 12-degree change.
Planned Rise Over Run
The fixed angle can contribute to a planned rise over a horizontal run when incorporated into a complete reviewed truss design.
System Limits
The corner defines component geometry. It does not independently establish the completed system’s support, span, drainage, wind, or loading limits.

Where Is This 12-Degree Corner Used?

For Planned Sloped Truss Layouts with a Fixed 12-Degree Transition.

Use the EVT290X-12DA Black in compatible truss layouts where a planned roofline, canopy line, stage structure, exhibit, lighting framework, AV structure, or display requires a fixed 12-degree directional change. The matte black finish is suited to production, event, exhibit, stage, lighting, AV, and display environments where black truss is preferred.

01
Sloped Truss Roof Frames
Use in a planned roof-frame geometry where a fixed 12-degree truss transition is specified.
02
Canopy Structures
Use in a planned canopy truss layout requiring a controlled fixed-angle transition.
03
Stage and Scenic Structures
Use in compatible stage frames, scenic structures, backdrop systems, and presentation layouts with black truss.
04
Lighting and AV Frameworks
Use in planned lighting, video, camera, projection, audio, and cable-management truss layouts.

Why Choose Matte Black?

Choose a Finish That Helps the Truss Visually Recede.

Choose the EVT290X-12DA Black when the fixed-angle corner must match black truss components or when the truss should remain less visually prominent in a stage, exhibit, lighting, AV, display, or production environment. Matte black is a finish choice; it does not alter the component’s geometry, connection requirements, or project-specific engineering needs.

Match Black Truss
Use with compatible black truss sections and components where a coordinated dark finish is required.
Reduce Visual Presence
Select matte black where exposed truss should visually recede within the stage, exhibit, or display environment.
Different From Brushed Aluminum
Brushed aluminum is selected for a visible natural-metal appearance. Matte black is selected for a darker visual treatment.
Finish Does Not Set Capacity
Finish selection does not change load capacity, connection requirements, inspection requirements, engineering review, or safety obligations.

System Compatibility

F34, EVT290S, and Compatible 290 mm Square Truss Systems.

The EVT290X-12DA Black has 290 mm square-truss geometry and conical connection receivers. It is intended for compatible F34, EVT290S, and standard 290 mm square-truss systems with matching receiver spacing and conical interface geometry. Confirm actual receiver geometry, full conical seating, pin engagement, component condition, and manufacturer or engineering data before combining separately sourced or mixed-brand components.

F34 System Context
Designed for use where the mating F34 connection geometry and receiver spacing match.
EVT290S Compatibility
Integrates with compatible EVT290S sections and related 290 mm square-truss components.
Matched Conical Interfaces
Connection suitability requires matching interfaces, full seating, coupler-pins, and R-clips.
50 mm Clamp Context
Use compatible 50 mm clamps only where placement and loading are approved for the complete structure.

How Is the 12-Degree Corner Connected?

Plan the Connection, Then Inspect Every Required Point.

Assembly should be completed by trained personnel using compatible components, the project drawing, the approved support or rigging plan, and sufficient hardware for every required connection. The supplied hardware covers one connecting side only.

01 — Inspect Components
Check chords, braces, welds, receivers, conical couplers, coupler-pins, and R-clips. Do not use damaged, worn, contaminated, or improperly fitting components.
02 — Confirm the Layout
Position the corner to match the approved 12-degree project layout before connection work begins.
03 — Plan Hardware
Use supplied hardware for its one included connecting side. Identify compatible hardware for every remaining required connection position.
04 — Align Mating Truss
Bring compatible truss faces together evenly. Connections should close without forcing, spreading, or pulling components into alignment.
05 — Secure the Connection
Fully install each required coupler-pin and secure every installed coupler-pin with its R-clip.
06 — Final Inspection
Verify retention, component condition, support planning, and the completed fixed-angle configuration before movement, lifting, rigging, or load application.
If a Connection Does Not Close
Stop assembly. Check receiver spacing, coupler fit, debris, hardware condition, damage, and alignment. Do not modify the component or drive a coupler-pin against resistance.

Safety and Engineering

A Fixed 12-Degree Corner Is Not a Standalone Load, Span, or Roof Rating.

The EVT290X-12DA Black does not independently establish a span, load, wind, drainage, weatherproofing, suspension, freestanding-structure, roof, or canopy rating. Determine suitability from the complete configuration, including connected components, spans, orientation, supports, connection hardware, bracing, rigging method, applied loads, lighting, AV equipment, displays, signage, base plates, ballast or anchorage, coverings, environmental conditions, venue requirements, and applicable approvals.

Do not use a straight-section load-span table to independently rate this fixed-angle corner or the completed truss system.
Do not treat an individual corner as evidence that a sloped roof, canopy, stage structure, AV framework, exhibit structure, suspended configuration, or public-facing structure has adequate capacity.
Confirm project-specific support, rigging, bracing, base-plate, ballast, anchorage, covering, and drainage plans before erection or loading.
Assess wind, weather, banners, screens, displays, suspended equipment, public access, and other operational or environmental forces as part of the complete project review.
Inspect every conical coupler, coupler-pin, R-clip, clamp, base connection, sling, shackle, safety cable, and attachment point before use.
Use trained personnel and obtain the project-specific engineering, facility, venue, and regulatory review required for the intended use.
Documentation and Project Review
