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 enables flexible height adjustment to accommodate various chassis specifications, offering effective rear support for the graphics card. High-quality aluminum-magnesium alloy material. The magnesium-aluminum alloy construction delivers strong and durable support. The surface undergoes sandblasting and anodization for a refined texture and long-lasting finish. Enhanced support and protection. The top contact 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, allowing secure attachment to steel surfaces such as the power supply compartment or chassis base plate for stable support. Safe and reliable magnetic attachment. Non-slip rubber pads on both ends ensure stability during installation and help prevent movement inside the chassis. The magnetic base securely adheres to ferromagnetic surfaces like steel power supply housings and chassis plates, providing firm support. Instructions for rotating screw: Rotate the telescopic screw counterclockwise to achieve the desired height, then turn the middle locking ring clockwise to secure and lock the position.
