Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to provide adjustable support height ranging from 74mm to 120mm. This adjustable height adapts to various chassis specifications, offering effective rear support for the graphics card. High-quality aluminum-magnesium alloy material. The magnesium-aluminum alloy construction ensures strong, durable, and long-lasting support. The surface undergoes sandblasting and anodization for a premium texture and enhanced durability. Enhanced support and protection. The top contact point includes a silicone pad to prevent damage to the graphics card. The bottom of the bracket features a magnet combined with a silicone sheet, enabling secure attachment to ferromagnetic surfaces such as the power supply compartment or chassis base, ensuring stable support. Safe and reliable magnetic attachment. Non-slip rubber pads on both ends facilitate easy installation and help keep the bracket firmly in place within the chassis, minimizing movement and preventing contact with the graphics card. The magnetic base securely adheres to compatible metal surfaces, providing consistent support. Instructions for rotating screw: Turn the telescopic screw counterclockwise to achieve the desired height, then rotate the central locking ring clockwise to secure and lock the position.
