Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to support a height range of 74–120mm. Height can be freely adjusted to accommodate various chassis specifications, providing effective rear support for graphics cards. High-end aluminum-magnesium alloy material. The magnesium-aluminum alloy construction offers strong and durable support. The surface undergoes sandblasting and anodization for a refined texture and long-lasting finish. Thoughtful support protection. The top contact point is fitted with a silicone pad to prevent damage to the graphics card. The bottom of the bracket includes a magnet combined with a silicone sheet, enabling it to securely attach to metal surfaces such as power supply compartments and chassis base plates. Safety protection with stable magnetic adhesion. Non-slip rubber pads are located at both ends for secure placement and easy installation, helping to prevent movement inside the chassis and avoid contact with the graphics card. The magnetic base allows firm attachment to ferromagnetic materials like steel chassis components. Instructions for use: Rotate the telescopic screw counterclockwise to achieve the desired height, then turn the middle locking ring clockwise to secure and lock the position.
