The FD 43 Circular Truss series by Naxpro Truss is the Triangular Truss (3-Point) structure with the largest cross-section in the Fair Duty (FD) line. This truss is engineered to handle extremely heavy loads and offers maximum structural rigidity for large-scale circular structures.

The FD 43 is essential for major productions and complex rigs where structural reliability and the ability to span long distances are critical.

⚙️ Features and Structural Improvement

Feature FD 43 Detail Comparison with FD 33
Structure 3 Point Circular (Triangular Truss), classified as Fair Duty (FD). Maintains the triangular geometry.
Section Dimensions Extra-large triangular section (approx. 39 cm side length). Much Larger (FD 33 is approx. 29 cm). The increased cross-sectional dimension maximizes resistance to bending and deflection.
Main Tubes Three parallel tubes of 50 mm diameter with a wall thickness of 2 mm. The main tube diameter is the same.
Load Capacity Extremely High. The size increase to a 39 cm section provides a load capacity that rivals many Heavy Duty ranges, making it ideal for very heavy concert lights, speaker arrays, or large scenic elements. Maximum. Significantly increases capacity for long spans.
Curve Types Available in A/A (Up/Down), INT (Interior), and EXT (Exterior) versions (circles from 2m to 10m Outer Diameter). Same as the FD 33.
Ideal Application The most powerful triangular truss in the FD range, perfect for main stage structures, large exhibition booths with heavy suspension requirements, and industrial rigging applications that prioritize high load capacity and rigidity. Provides maximum safety and stiffness in large circular constructions.
Connection Standard conical connection system, compatible with straight sections of the FD 43 series. Maintains compatibility with the rest of the FD 4X series.
