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, it delivers strong, durable, and long-lasting stability. The surface undergoes sandblasting and anodizing for a refined texture and enhanced durability. The top support point includes a silicone pad to prevent damage to the graphics card. The bottom incorporates a magnet combined with a silicone sheet, enabling secure attachment to ferromagnetic surfaces such as the power supply compartment or chassis base. Non-slip rubber pads on both ends ensure stability and prevent slipping during installation. The magnetic base securely adheres to compatible metal surfaces, providing reliable support. To use the rotating screw: turn the telescopic screw counterclockwise to the desired height, then rotate the middle locking ring clockwise to secure. Name: Graphics Card Protection Bracket.
