Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to provide support within a height range of 74–120mm. Height is adjustable to accommodate various chassis specifications, offering effective rear support for the graphics card. Constructed from high-quality aluminum alloy, it delivers strong and durable performance. The surface undergoes sandblasting and anodization for enhanced texture and long-lasting finish. The top contact point includes a silicone pad to prevent damage to the graphics card. The bottom incorporates a magnet combined with a silicone sheet, enabling secure attachment to ferromagnetic surfaces such as power supply compartments and chassis base plates. This ensures stable and reliable support. Non-slip rubber pads on both ends aid in easy installation and help maintain stability inside the chassis, reducing the risk of slippage or impact. To use the rotating screw: Turn the telescopic screw counterclockwise to reach the desired height, then tighten the central locking ring clockwise to secure the position.
