Durable and robust, the bracket is made from aluminum alloy with a sandblasted and anodized surface finish for enhanced texture and long-lasting performance. Enhanced support and protection. The top contact point includes a silicone pad to prevent damage to the graphics card. The bottom is equipped with a magnet and silicone sheet, enabling secure attachment to metal surfaces such as the power supply compartment or chassis base plate for stable support.
