Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 mini to provide a height support range of 26–50mm. Height can be freely adjusted to accommodate various chassis specifications, offering effective support for the rear of the graphics card. High-quality aluminum alloy material. The aluminum alloy construction ensures strong and durable support. The surface is sandblasted and anodized for a refined texture and long-lasting finish. Enhanced support protection. The top contact point is lined 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 power supply compartments and chassis base plates. Non-slip and stable magnetic design. Non-slip rubber pads on both ends ensure stability during installation and help prevent movement inside the chassis. The magnetic base securely attaches to ferromagnetic materials, providing reliable support. Instructions: Rotate the telescopic screw counterclockwise to achieve the desired height, then turn the middle locking ring clockwise to secure in place.
