The Light Source Mega-Sidearm 18" Fixed Length in Black Anodized finish is a rigid, heavy-duty extension arm designed for positioning equipment at a fixed distance from a primary support structure. Unlike adjustable arms, this 18-inch (approximately 46 cm) arm is a single, solid piece of machined aluminum or steel, providing maximum stability and zero deflection under load. Its primary function is to act as a robust cantilever, allowing lighting fixtures, cameras, speakers, or other accessories to be mounted well clear of truss, pipe, or wall mounts to achieve optimal placement and coverage without the need for additional, potentially less stable, scaffolding.

The black anodized coating offers a durable, corrosion-resistant finish that is both aesthetically subtle and professionally sleek, suitable for permanent installations and high-visibility applications. The arm typically features standardized mounting points at each end, such as a Mega-Coupler or large pin hole at the structure end and a 1/2-inch stud or similar fitting at the equipment end. This fixed-length design eliminates any potential slippage or creep that can occur with telescoping or adjustable arms, ensuring the mounted equipment's position remains absolutely consistent over time, which is critical for calibrated systems like laser alignment or fixed camera shots.

This sidearm is a fundamental tool for system designers and installers who require predictable, repeatable, and rock-solid positioning. Common applications include extending moving lights out from a truss to avoid beam obstruction, mounting speakers away from a wall to improve sound dispersion, or positioning surveillance cameras at a precise distance from a building facade. The Mega-Sidearm's robust construction guarantees that once secured, it will not sag, vibrate, or rotate, maintaining the integrity of the installation. It provides a simple, ultra-reliable solution for creating permanent offset mounts in architectural, theatrical, and commercial AVL installations.
