Questions about this item

How do I attach the desk clamp to a desk that is 0.6 to 2.6 inches thick?

Position the clamp over the desk edge, tighten the thumb screw until the rubber pads grip firmly, then torque the set screw with the supplied hex key to lock the arm base; the clamp accepts surfaces from 0.6 to 2.6 inches thick.

What parts might wear out after years of daily height adjustments?

The gas-spring cylinder and pivot bearings are rated for 10,000 full-range cycles, roughly three moves per day for ten years; if motion becomes uneven, the cylinder can be replaced as a service part.

At what monitor weight does the arm stop holding position without constant readjustment?

The arm is calibrated for 28 to 42 pounds; loads outside that range will either sag or resist movement, so verify your ultrawide’s weight including any accessories before mounting.
