Heavy-duty monitor arm for large displays

Gas-spring mechanism with wide articulation

A gas spring enables smooth height adjustment from 7.6 to 18.9 inches with minimal effort. The mount provides ±90° swivel, +50/-20° tilt and ±180° rotation for landscape or portrait orientation. Cable management channels keep routing tidy during movement.

SmartFit ergonomics and included hardware

Questions about this item

How do I attach the C-clamp to a desk, and what clearance mistake do installers make?

The topside C-clamp fits surfaces .5 to 2 inches thick; the common error is not checking desk thickness before mounting, which prevents a secure grip.

What parts wear out first and will need replacement after heavy use?

The gas-spring cylinder that enables smooth height adjustment from 7.6 to 18.9 inches is the primary wear item; it can lose pressure over time and require replacement.

At what point does the arm hit its limit when I keep adjusting the monitor position daily?

The gas-spring height range tops out at 18.9 inches (481 mm); beyond that the arm cannot raise the monitor further, which is the first hard stop under sustained repositioning.
