EVT290A-CON Conical Truss Connector.
For Joining EVT290I, EVT290T, EVT290S, and F34 Truss Segments.

The EVT290A-CON is the standard double-sided conical connector used to join two 290 mm truss segments end-to-end. Riggers often call it an egg, spigot, or truss connector. Precision-machined from Aluminum Alloy 6061-T6, it seats into the conical receivers of two adjoining truss sections and is secured with the included coupler-pins and r-clips, driven in with a steel hammer — the same connection used throughout compatible EVT290I, EVT290T, EVT290S, and F34-format truss systems.

Product Overview

The Core Link Between Two 290 mm Truss Segments.

The EVT290A-CON is a double-sided conical coupler that joins two truss receivers end-to-end. Once seated, it is secured with a coupler-pin and r-clip at each side. A steel hammer is required to drive each coupler-pin fully into place; no other tool provides the mass needed to seat the pin correctly.

Double-Sided Design
Joins two truss receivers end-to-end, forming the standard linear connection point in a 290 mm truss run.
Steel Hammer Installation
Coupler-pins must be driven in with a steel hammer to seat fully and lock correctly.
Aluminum Alloy 6061-T6
Precision-machined for high mechanical strength and fatigue resistance under repeated assembly.
F34 Compatible
Designed for compatible integration with EVT290I, EVT290T, EVT290S, and most standard 290 mm truss systems.

Common Applications

Join Truss Sections and Restock Essential Spares.

The EVT290A-CON is used at every standard linear connection point in a 290 mm truss run, and it is one of the most frequently replaced components in a working truss inventory. Confirm connection hardware, component condition, and complete support requirements as part of the approved truss system.

01
Straight Truss Runs
Join adjoining truss sticks end-to-end to build straight spans of any required length.
02
Corners, Bases, and Accessories
Connect straight truss to corners, base plates, and other compatible accessories using the same conical joint.
03
Load-In Spares
Keep on hand as a critical spare part for replacing lost, damaged, or worn connectors during a load-in.
04
Inventory Expansion
Add connection hardware when expanding an existing 290 mm truss inventory.

Included Connection Hardware

One Complete Kit for One Connection Point.

The EVT290A-CON includes one complete connection kit: 1 Conical Coupler, 2 Coupler-Pins, and 2 R-Clips — everything needed for one connection point between two truss receivers. A steel hammer is required for installation but is not included. Confirm the current product package and connection requirements before assembly.

1 Conical Coupler
The double-sided coupler body that seats into both adjoining truss receivers.
2 Coupler-Pins
Secure the coupler at each connection side; one coupler-pin per truss receiver, driven in with a steel hammer.
2 R-Clips
Retain the installed coupler-pins; one r-clip per pin. Confirm both are installed before loading or lifting.
Spring Wire R-Clips
Made from durable spring wire for reliable retention and locking at each connection.

System Compatibility

EVT290I, EVT290T, EVT290S, and F34 Truss Systems.

The EVT290A-CON is designed for compatible EVT290I I-Beam, EVT290T Triangular, EVT290S Square, and F34-format 290 mm truss systems, serving as a replacement or expansion part across the EVT290 series. Confirm receiver dimensions, conical connector details, and applicable structural data before combining components from different systems.

EVT290I System
The connector is compatible with the EVT290I I-Beam aluminum truss profile.
EVT290T System
The connector is compatible with the EVT290T triangular aluminum truss profile.
EVT290S System
The connector is compatible with the EVT290S nominal 290 mm square-truss profile.
F34 System
The product is intended for F34-style 290 mm truss systems with matching connection details.
Physical Fit Does Not Establish Structural Equivalence
Do not mix truss components from different manufacturers if the tolerance varies. A component may physically connect to another 290 mm truss component without the complete assembly having equivalent structural properties. Always test-fit connections with other brands on the ground to confirm coupler-pin alignment is exact.

Connection and Assembly

Seat, Pin, and Verify Every Connection Before Use.

Assembly should be completed by trained personnel using matching components and the approved truss system. The coupler is the primary load-transfer point between truss sticks — never use a damaged, dented, or deformed coupler, as this compromises the entire span.

01 — Inspect Components
Check the coupler, coupler-pins, and r-clips for egging (elongation of the pin holes), burrs, or deformation before use.
02 — Seat the Coupler
Fit the coupler into the conical receivers of both adjoining truss sections. It should seat fully with light taps of a steel hammer, not excessive force.
03 — Drive the Coupler-Pins
Using a steel hammer, drive a coupler-pin fully into place through each connection side once the coupler is seated.
04 — Secure the R-Clips
Lock each installed coupler-pin with its r-clip.
05 — Locking Check
Confirm both coupler-pins are fully inserted and locked with r-clips before raising the structure.
06 — Verify Before Loading
Confirm both connection sides are fully seated and secured, and the complete support arrangement is approved, before loading or lifting.

Safety and Engineering

The Coupler Is a Primary Load-Transfer Point.

The EVT290A-CON does not independently establish a load or span rating. It transfers load directly between truss sticks, so a damaged, worn, or improperly secured coupler can compromise an entire span. Confirm all connection, inspection, and engineering requirements as part of the complete approved truss system.

Use a steel hammer to seat the coupler and drive each coupler-pin fully into place; use light taps for the coupler and firm, direct strikes for each pin.
Never use a damaged, dented, or deformed coupler, as this compromises the entire span.
Always ensure both coupler-pins are fully inserted and locked with r-clips before raising the structure.
Inspect couplers for egging (elongation of the pin holes) or burrs before use.
Do not mix truss components from different manufacturers if the tolerance varies.
Discard couplers that show signs of significant wear or impact damage.
While F34 compatible, always test-fit connections with other brands on the ground to ensure pin alignment is exact.
All truss structures must be reviewed by a qualified rigger or engineer.
Verify Current Documentation Before Ordering or Installing
Confirm current manufacturer drawings, instructions, and included hardware against the actual product package before ordering or installing the EVT290A-CON. Verify compatibility with the specific EVT290I, EVT290T, EVT290S, or F34-format truss components being used, and inspect every coupler, coupler-pin, and r-clip before each use. Suspended, public-facing, outdoor, or other load-bearing structures using this connector require project-specific review by qualified rigging or engineering personnel before use.
