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 freely adjustable to accommodate various chassis specifications, offering effective support for the rear of the graphics card. Constructed from high-end aluminum-magnesium alloy material, it delivers strong, durable, and long-lasting support. The surface undergoes sandblasting and anodizing for a premium texture and lasting finish. 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 ferromagnetic surfaces such as the power supply compartment or chassis base plate. Magnetic attachment is stable and safe, providing reliable support. Non-slip rubber pads on both ends ensure stability and ease of installation, helping to prevent movement and protect the graphics card. To adjust, rotate the telescopic screw counterclockwise to the desired height, then tighten the middle locking ring clockwise to secure. Name: Graphics Card Protection Bracket. Model: GX-30 Plus.
