Mounting Arm Extension Module DNA EXA1 SI — accessory for truss systems

DNA EXA1 SI is an extension mounting arm module designed to attach to standard truss and rigging systems. The module provides a rigid lateral extension that enables mounting and positioning of lighting fixtures, speakers or auxiliary equipment at an offset from the main truss structure. Constructed for event and installation use, the accessory supports secure fixation and accurate placement where additional reach or clearance is required.

Advantages

The extension arm offers a stable lateral projection that preserves load alignment and reduces torque on the primary truss. Its design simplifies adding equipment without modifying the main truss run, enabling flexible positioning and faster rigging changes. The module is compatible with common stage and event practices, providing predictable mounting geometry and repeatable results during setup and teardown.

Suitable for

• Attaching lighting fixtures at an offset from the truss
• Mounting speakers or monitor enclosures where forward reach is needed
• Adding auxiliary equipment such as cameras, projectors or small effects devices
• Temporary event rigs, touring setups and fixed installations requiring lateral extensions

Key specifications

• Function: lateral extension/mounting arm for truss systems
• Material: robust metal construction suitable for rigging loads
• Attachment: designed to interface with standard truss connection points
• Usage environment: indoor and outdoor event and installation settings
• Purpose: supports lighting, audio, and auxiliary equipment mounting

How to use

Attach the extension module to the truss at a suitable connection point, ensuring alignment with the primary load path. Secure all fasteners and locking mechanisms according to the truss system procedures and rated hardware specifications. Mount fixtures or devices to the extension arm using compatible clamps, bolts or brackets, and verify that the combined load remains within the rated capacity of the truss and the module. Perform a visual and physical inspection after installation and before each use.

Usage recommendations

Verify compatibility with the primary truss system and follow all applicable rigging safety standards. Use rated hardware and, where appropriate, secondary safety attachments such as safety cables. If uncertain about load calculations or installation, consult a qualified rigger or structural engineer.
