Vertical Stacked Dual Monitor Arm

The BFKK vertical stacked dual monitor arm supports two 13 to 49 inch ultrawide curved or flat monitors weighing up to 44lbs each. It attaches via 75x75mm or 100x100mm VESA patterns and fits desks using a C-clamp up to .82in thick or a grommet mount for 0.4 to 2.4in surfaces.

Sustained Adjustment Stability

Premium gas springs are tested beyond 20,000 cycles to eliminate rebound and maintain consistent tension across the full height range of 2.4 to 28in. The arm delivers smooth tilt from +90 to -45 degrees, 180 degree swivel and 360 degree rotation without drift during extended daily repositioning.

Thermal Noise And Power Draw

This mechanical mount operates silently with no electrical components, fans or power draw. Integrated cable channels route wires internally along the 18in pole to keep the workspace tidy while the all-metal construction dissipates negligible heat during normal adjustments.

Questions about this item

Does the gas-spring arm stay quiet and cool when adjusted repeatedly through its full 2.4-28" height range?

Premium gas springs tested over 20,000 cycles eliminate rebound and provide ultra-smooth, silent adjustments without heat buildup.

My desk is 2.4" thick — can I still use the grommet mount with the supplied hardware?

Yes, the grommet mount accepts desks 0.4-2.4" thick and the C-clamp fits up to .82"; both methods are tool-free.

Will my existing 13" monitor with 75x75mm VESA holes work on the upper arm alongside a 49" ultrawide on the lower arm?

Both arms support 75x75mm and 100x100mm VESA patterns and each carries up to 44lbs, so mixed sizes are fully compatible.
