Stack Jack Mini is designed specifically for computers with a single graphics card 200 mm or larger that sags at the unsupported end. This model uses a custom thread design that provides 1 mm vibration resistant adjustments every one third turn. The movable adjustment parts fit together in such a way that when under pressure they will not move freely.

The modular design, (parts a, b, and c), has a range of 5.5" - 8.5" and can be increased using the 2" (50mm) extension.

The compact design, (parts a and cb), has a range of 4.5" - 7.25".

WARNING: The small diameter of this design can make printing very difficult.
