Antec's flyer drawing sets two stands side by side, one extended to 100mm and one lowered to 63.5mm. Adjust the height until the pad meets the underside of your card, then set the stand in the case. The compact footprint leaves most of the case floor free.

These two views show the same stand in both positions. The tall one has its post pulled up with the pad at the top, and the short one sits low on its base. Both carry the Antec name on the front of the black body, so the stand reads as part of a dark build.

A close view of the body shows a round knob on the front of the base and the Antec logo below it. The base has a flared foot. Antec describes it as a magnetic non-slip base, which is what holds the stand where you put it inside the chassis.

Antec's Easy To Use slide says to adjust to the appropriate height and put it on the chassis. The rubber pad on the top and the magnetic base structure make it safe and steady. The inset arrows mark the post moving up and down, and the callouts name the Stable Rubber Pad and the Magnetic Non-slip Base.

Here the stand sits under the shroud of an RTX card inside a case, with its post holding the card level. Antec says a tilted card hurts your motherboard and blocks the inside airflow, while the stand keeps the card stable and safe and ensures chassis heat dissipation.
