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 allows for flexible height adjustment to accommodate various chassis specifications, offering effective rear support for the graphics card. Constructed from high-quality aluminum alloy, the bracket delivers strong, durable, and long-lasting support. The surface undergoes sandblasting and anodization 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 is equipped with a magnet and silicone sheet, enabling secure attachment to metal surfaces such as the power supply compartment or chassis base plate for stable support. Non-slip rubber pads on both ends ensure stability and prevent slipping during installation, helping to protect the graphics card from impact. The magnetic base securely adheres to ferromagnetic surfaces, providing reliable support. Instructions for use: Rotate the telescopic screw counterclockwise to achieve the desired height, then tighten the middle locking ring clockwise to secure the position.
