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 fit various chassis specifications, providing effective support for the rear of the graphics card. High-end aluminum-magnesium alloy material. Magnesium-aluminum alloy ensures strong and lasting support, offering a sturdy and durable build. The surface is sandblasted and anodized for a premium texture and long-lasting finish. Thoughtful support protection. The top support point includes a silicone pad to prevent damage to the graphics card. The bottom of the bracket features a magnet combined with a silicone sheet, allowing it to securely attach to metal surfaces such as the power supply compartment or chassis base, ensuring stable support. Safety protection with reliable magnetic adhesion. Non-slip rubber pads are located at both ends for secure installation and stability inside the chassis, helping to prevent accidental contact with the graphics card. The magnetic base allows attachment to iron-based materials like the power supply housing or chassis plate, providing firm adhesion and dependable support. Instructions for use: Rotate the telescopic screw counterclockwise to reach the desired height, then tighten by rotating the center locking ring clockwise to secure in place.
