Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, enabling adjustable height support from 74 mm to 120 mm. This allows compatibility with various chassis sizes and provides effective rear support for the graphics card. Premium aluminum alloy construction ensures strong, durable, and long-lasting support. The surface undergoes sandblasting and anodizing for enhanced texture and corrosion resistance. Silicone padding is applied at the top contact point to protect the graphics card from scratches or impact. The base incorporates a magnet combined with a silicone sheet, allowing secure attachment to ferrous surfaces such as power supply compartments or chassis bottom plates. Non-slip rubber pads are integrated at both ends for stable placement and ease of installation. Magnetic base ensures firm adhesion to compatible metal surfaces. Usage instructions: Rotate the telescopic screw counterclockwise to reach the desired height, then tighten the central locking ring clockwise to secure the position.
