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. Offers effective support for the rear of the graphics card to help prevent sagging. Constructed from high-quality aluminum-magnesium alloy for strong, durable, and long-lasting performance. Surface treated with sandblasting and anodization for enhanced texture and durability. The top contact point includes a silicone pad to protect the graphics card from scratches or damage. The bottom features a magnet combined with a silicone sheet, allowing secure attachment to ferromagnetic surfaces such as the power supply compartment or chassis base plate. Provides stable and reliable magnetic adhesion for firm support. Non-slip rubber pads on both ends ensure stability and prevent movement inside the chassis. To use the adjustment screw: rotate the telescopic screw counterclockwise to reach the desired height, then turn the center locking ring clockwise to secure the position.
