Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to provide a support 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, the bracket delivers strong, long-lasting support. The surface undergoes sandblasting and anodization for a durable, refined texture. The top support point includes a silicone pad to prevent damage to the graphics card. The bottom features a magnet combined with a silicone sheet, enabling secure attachment to ferromagnetic surfaces such as power supply compartments and chassis base plates. Non-slip rubber pads on both ends ensure stability and prevent shifting during installation, helping to protect the graphics card from impact. Magnetic base provides firm adhesion to compatible metal surfaces. Instructions: Rotate the telescopic screw counterclockwise to reach the desired height, then tighten the central locking ring clockwise to secure the position.
