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.
