Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to provide adjustable support height from 74mm to 120mm. This enables flexible height adjustment to accommodate various chassis specifications, offering effective rear support for the graphics card. High-quality aluminum-magnesium alloy material. The magnesium-aluminum alloy construction delivers strong, durable support with a sandblasted and anodized surface finish for a premium, long-lasting texture. Enhanced support and protection. The top 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, allowing secure attachment to metal surfaces such as the power supply compartment or chassis base plate for stable support. Safe and reliable magnetic attachment. Non-slip rubber pads on both ends ensure stability and prevent scratching during installation. The magnetic base securely adheres to ferromagnetic materials like steel chassis components, providing firm support without risk of slippage. Instructions for use: Rotate the telescopic screw counterclockwise to achieve the desired height, then tighten the central locking ring clockwise to secure the position.
