Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to provide adjustable support ranging from 74mm to 120mm. This height adjustability ensures compatibility with various chassis specifications, offering effective rear support for the graphics card. High-quality aluminum alloy material. The aluminum alloy construction delivers strong, durable support. The surface is sandblasted and anodized for a refined texture and long-lasting finish. Enhanced support and protection. The top support contact point is lined 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 secure attachment to metal surfaces such as power supply compartments and chassis base plates. Secure, non-slip, and stable magnetic design. Non-slip rubber pads on both ends assist in easy installation and ensure stability within the chassis, preventing accidental contact with the graphics card. The magnetic base securely adheres to ferromagnetic surfaces, providing reliable support. Instructions for use: Rotate the telescopic screw counterclockwise to achieve the desired height, then tighten the central locking ring clockwise to secure the position.
