Product Description
EVT290S-Block Black Universal Junction Block | 290 mm Square Aluminum Truss
The EVT290S-Block Black Universal Junction Block is a precision-engineered 6-way modular connector designed for EVT290S 290 mm square conical aluminum truss systems. This versatile component serves as the structural “hub” of a truss build, functioning as a 2-way or 3-way 90-degree corner, a 4-way cross, or a 5/6-way junction. Its multi-directional capability eliminates the need for multiple specific corner types, providing maximum flexibility while maintaining full system compatibility.
Manufactured from high-grade 6082-T6 aluminum alloy and fabricated in accordance with TUV specifications, the EVT290S-Block Black delivers dependable structural performance and geometric accuracy. It features a secure conical connection system and includes two full sets of connecting hardware (Conical Couplers, Pins, and R-clips) to facilitate fast, repeatable assembly in professional production environments.
Finished in a durable black powder-coated finish, this junction block integrates seamlessly into lighting, staging, and AV systems where both structural performance and visual consistency are critical. It is designed for use with EVT290S 290 mm square truss sections in applications such as event production, staging, lighting grids, video wall support structures, trade-show exhibits, and complex modular truss installations.

⚠️ Safety & Engineering Notice
❗ Critical Load Rating Information: The rated load capacity of this junction block depends on the complete system configuration and the orientation of the attached spans. Always consult applicable EVT290S load tables and a qualified engineer when determining load limits for complex junctions.
Important Guidelines for Safe Use:
- Never exceed the rated load capacity of the truss system.
- No loads shall be supported directly from truss connection points.
- Inspect all truss components before each use and remove damaged parts from service.
- Handle truss components with care—avoid dropping, dragging, or improper stacking.
- Assembly and installation must be performed only by trained and qualified personnel.
- Ensure all Couplers, Pins, and R-clips are correctly installed and fully secured.
- Account for all applicable forces, including dynamic and transverse forces such as wind loads.
- Do not mix truss components from different manufacturers.
- All truss structures must be reviewed and approved by a licensed professional engineer.
⚠️ Compatibility Warning for Mixed-Brand Builds
Crucial Steps for Safe Assembly:
- Verify all dimensions before integrating with other truss brands.
- Confirm conical connector type, node spacing, and system geometry.
- Mixing components without verification may compromise structural integrity and safety.
