The Light Source Mega-Sidearm 12" Fixed Length is a heavy-duty mounting arm engineered for permanent and semi-permanent installations where fixture stability and a precise, unchanging offset are paramount. It functions as a rigid extension to mount lighting fixtures, speakers, or peripheral equipment perpendicularly from a primary truss or structural pipe, effectively creating a second tier of gear. Its fixed-length design eliminates any risk of slippage or accidental shortening during operation, a critical safety feature when suspending equipment overhead in theaters, concert venues, or studio environments. The robust construction ensures reliable performance under sustained load, making it a fundamental component for technical directors and riggers planning complex system layouts.

Manufactured from high-strength aluminum, the sidearm achieves a durable yet lightweight form that simplifies handling during installation without compromising its load-bearing integrity. The component features a sleek black anodized finish that provides excellent corrosion resistance against environmental factors and minimizes light spill and reflection in dark performance spaces. One end is designed with a standard clamp mechanism for secure attachment to a pipe or truss member, while the opposite end offers a fixed receiver or bolt pattern to interface directly with a fixture's yoke or an accessory plate. This straightforward, no-nonsense design prioritizes reliability and ease of use in professional applications.

This product is ideal for creating clean, repeatable lighting positions, allowing designers to maximize fixture density on a given truss and achieve specific angles that cannot be accomplished with standard vertical hanging. Its primary use is in architectural lighting grids, theatrical rigging systems, touring concert setups, and any installed environment where equipment must be positioned away from its support to clear obstacles or other installed elements. The Mega-Sidearm provides a simple, effective, and trusted mechanical solution for achieving consistent and safe lateral positioning in a wide array of technical production scenarios.
