Will it hold my 27-inch monitor?

Yes, if the monitor weighs between 2 and 6.5 kg (4.4–14.3 lbs) and has a VESA 75x75 or 100x100 pattern. Check the panel's weight without the stand before buying.

Can I mount it without drilling into the desk?

Yes. The clamp fits over a desk edge, and a grommet bolt is included for desks that already have a cable hole. The clamp needs a solid edge of reasonable thickness.

Does it work for portrait orientation?

Yes. Each arm rotates, so you can set one or both screens vertically. The 360° swivel also lets you angle screens toward each other.

How much desk depth does it need?

The clamp sits at the desk edge and the arms reach forward, so leave room behind the screens for the arm to fold. A deeper desk gives more positioning freedom.

Is it good for standing desks?

The gas spring lets you raise and lower the screens quickly as you change posture. Make sure the desk itself is stable, since dual arms amplify any wobble.
