Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to provide adjustable height support from 74 mm to 120 mm. Height is freely adjustable to accommodate various chassis specifications, offering effective rear support for the graphics card. Premium aluminum-magnesium alloy construction. The bracket is made of durable aluminum-magnesium alloy, providing strong, long-lasting structural support. Surface finished with sandblasting and anodization for enhanced texture and corrosion resistance. Thoughtful protection design. A silicone gasket is integrated at the top contact point to prevent direct contact and potential damage to the graphics card. The base features a magnet combined with a silicone pad, enabling secure attachment to ferrous surfaces such as power supply compartments or chassis bottom plates. Enhanced stability and safety. Non-slip rubber pads are included at both ends for secure placement and easy installation inside the chassis, minimizing movement and protecting the graphics card. Magnetic base ensures firm adhesion to compatible metal surfaces. Usage instructions: Rotate the telescopic screw counterclockwise to adjust to the desired height, then tighten the central locking ring clockwise to secure the position.
