Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to support a height range of 74–120mm. Height can be freely adjusted to accommodate various chassis specifications, providing effective support for the rear of the graphics card. Made from high-end aluminum alloy material, it offers strong, lasting support and is sturdy and durable. The surface is sandblasted and anodized for a premium texture and long-lasting finish. The top support surface includes a silicone gasket to help prevent damage to the graphics card. The bottom of the bracket features a magnet and silicone base, designed to securely attach to metal surfaces such as power supply compartments and chassis plates for stable support. Non-slip rubber pads on both ends help prevent slipping and ensure stability during installation. The magnetic base allows firm adhesion to iron-based materials, enhancing safety and stability. 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 – GX-30 Plus.
