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 enables flexible adjustment to fit various chassis specifications, offering effective rear support for the graphics card and helping to prevent sagging. Constructed from high-quality aluminum-magnesium alloy, the bracket delivers strong and durable support. The surface undergoes sandblasting and anodization for enhanced texture and long-lasting finish. The top support point includes a silicone pad to protect the graphics card from scratches or impact. The bottom of the bracket is equipped with a magnet combined with a 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 movement inside the chassis, protecting the graphics card during installation and use. The magnetic base securely adheres to ferromagnetic materials, providing reliable and slip-resistant support. Instructions for use: Rotate the telescopic screw counterclockwise to reach the desired height, then tighten the middle locking ring clockwise to secure the position.
