Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to provide adjustable support height from 74mm to 120mm. This enables flexible adjustment to fit various chassis specifications, offering effective rear support for the graphics card and helping to maintain stability. Constructed from high-quality aluminum-magnesium alloy material, the bracket delivers strong and durable support. The surface undergoes sandblasting and anodization for enhanced texture and long-lasting finish. Thoughtful protection design. The top contact point is fitted with a silicone pad to prevent damage to the graphics card. The bottom includes a magnet combined with a silicone sheet, enabling secure attachment to metal surfaces such as the power supply compartment or chassis base plate for reliable support. Safety and stability with magnetic suction. Non-slip rubber pads on both ends ensure stable placement and easy installation within the chassis, minimizing the risk of scratching or damaging components. The magnetic base securely adheres to ferromagnetic materials like steel chassis parts. Instructions for use: Rotate the telescopic screw counterclockwise to reach the desired height, then tighten by turning the central locking ring clockwise to secure the position.
