Product Description

Half Conical Coupler for Base Plate | Aluminum Truss Connector (EVT290A-BCON)

The EVT290A-BCON Aluminum Half Conical Coupler is the essential hardware link designed to secure 290 mm square truss to aluminum or steel base plates. Serving as the foundation for truss pillars, totems, and arch bases, this connector bolts directly onto the plate to create a rigid receiving point for standard truss segments.

Function & Compatibility:

This connector features a single-sided conical coupling machined from high-grade Aluminum Alloy 6061-T6. It attaches to the base plate using the included M10 x 20mm bolt (1.5 Thread Pitch), which is inserted through the underside of the plate. Once tightened, it provides a secure, upright connection. It is fully F34 Compatible, ensuring seamless integration with EVT290S and most standard 290mm box truss systems.

Key Features

• Base Plate Interface: Adapts flat base plates to receive standard conical truss segments.
• Compatibility: F34 Compatible design connects seamlessly with standard 290mm square truss straights and corners.
• Complete Kit: Includes 1x Half Coupler, 1x Truss Pin, 1x R-Clip, and 1x M10 Bolt.
• Premium Alloy Construction: Body machined from Aluminum Alloy 6061-T6 for maximum durability.
• High-Strength Hardware: Includes a Steel Grade S45C M10 Bolt (1.5 Pitch) for a secure anchor point.
• Half-Conical Design: Features one conical side for the truss and a flat machined bottom for the plate.

Designed by Evolve Truss, this connector is the standard replacement part for base plate assemblies and custom rigging points.

⚠️ Safety & Engineering Notice

❗ Critical Assembly Information:

• Bolt Tightness: The stability of a vertical tower relies heavily on this connection. Ensure the M10 bolt is fully tightened. For permanent installations, the use of a thread-locking fluid (Loctite) is recommended.
• Vibration Warning: Regularly check these bolts, as dynamic loads and vibrations can loosen them over time.

Important Guidelines for Safe Use:

• Ensure the base plate is sufficiently heavy or ballasted for the height of the truss tower being erected.
• Inspect components for thread damage or deformation before use.
• Ensure all Couplers, Pins, and R-clips are correctly installed and fully secured.
• Assembly and installation must be performed only by trained and qualified personnel.

⚠️ Compatibility Warning

Crucial Steps for Safe Assembly:

• Thread Verification: If replacing lost bolts, ensure you use the correct M10 x 1.5 Pitch specification.
• Brand Mixing: While F34 compatible, always test-fit connections with other brands to ensure proper pin alignment.
