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 accommodates various chassis specifications, offering effective rear support for the graphics card. High-quality aluminum-magnesium alloy material. The magnesium-aluminum alloy construction delivers strong, long-lasting support, ensuring durability and stability. The surface undergoes sandblasting and anodization for a refined texture and enhanced resilience. Enhanced support and protection. The top support point includes a silicone pad to prevent damage to the graphics card. The bottom of the bracket incorporates a magnet combined with a silicone sheet, enabling secure attachment to metal surfaces such as the power supply compartment or chassis base plate for reliable support. Secure magnetic attachment with non-slip protection. Non-slip rubber pads are located at both ends to ensure stability during installation and prevent movement inside the chassis. The magnetic base allows firm adhesion to ferromagnetic materials, providing dependable support. Instructions for adjusting the screw: Rotate the telescopic screw counterclockwise to achieve the desired height, then turn the center locking ring clockwise to secure the position.
