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. Height can be freely adjusted to fit various chassis specifications, offering effective support for the rear of the graphics card. Constructed from high-quality aluminum-magnesium alloy, it delivers strong, durable, and long-lasting performance. 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 of the bracket incorporates a magnet combined with a silicone sheet, enabling secure attachment to ferromagnetic surfaces such as power supply compartments and chassis base plates. This ensures stable and reliable support. Non-slip rubber pads on both ends enhance stability and protect the chassis during installation. To use the rotating screw: Turn the telescopic screw counterclockwise to reach the desired height, then tighten the central locking ring clockwise to secure the position.
