The cheapest mount here, 22 lb per arm, and a listing full of caveats
22 lb per arm — level with the Digitus, the highest on this shelf — at the lowest price here, on a listing that spends most of its bullets on what can go wrong.
Amazon Basics dual arm with independent tension, 22 lb per arm
Best for: Two heavy screens on a thick desk, for someone willing to set the tension properly before trusting it.
Two things make this listing unusual on this shelf, and they pull in opposite directions. It publishes 22 lb per arm — level with the Digitus for the highest rating here, against 19.8 lb on most of the arms around it — at the lowest price, about $40. And it spends every one of its five bullets explaining the conditions under which that rating means anything.
The conditions are all real. Tension has to be set per arm to the weight of each monitor or the screens drift. Stability does vary with how far the arms are extended. Deep-backed monitors do need longer screws or spacers to seat the VESA plate flush. Joints may arrive tight from the factory. Every mount on this shelf has these properties; this is the page that prints them.
What it leaves out is the number this hub asks for. There is no combined total anywhere, and no reach or rise figure either — the Acer and the MOUNTUP publish both, the two HUANUO arms their rise. The clamp range, on the other hand, is the widest here at 0.39 to 4.25 in, which covers a thick butcher-block top that rules out several of the others.

Because it is written around the ways a dual mount disappoints. Each bullet carries a condition: each arm "requires individual tension adjustment based on monitor weight", "Stability varies depending on monitor size, weight distribution, and arm extension", "Select appropriate screw length and use spacers if required", "Ensure secure installation and tightening before use", and "Joints may be pre-tightened and require adjustment before use". None of that is untrue of any mount on this shelf; this is the listing that says it.
Not necessarily, and the listing never claims it. This hub's buying tip exists for that reason: the load on the post and the clamp is the sum while the arm rating is per side. Only one mount on this shelf, the Mount-It standing frame, publishes a combined total (55 lb). For two 19 lb monitors on a 22 lb-per-arm mount, the per-arm figure is comfortable and the total is unstated.
Yes — 0.39 to 4.25 in (10 to 108 mm) is the widest clamp range on this shelf, enough for a thick butcher-block top. The grommet option is there for desks with a cable hole.
The longest reach and the greatest height range of the clamp mounts on this shelf — 21.25 in and 18.1 in — on a gas-spring arm stated to have passed 20,000 durability cycles.
Best for: A deep desk and a tall person, where reach and rise are the binding constraints.
The same dual C-clamp base and the same per-arm rating as its stablemate, with more rise — 16.2 in — a 27 in screen ceiling, and no manufacturer reference anywhere on the listing.
Best for: Two 24 or 27 in screens on a wooden desk, where a two-clamp base matters more than the last inch of rise.
A dual mount for flat or curved screens up to 35 in and 22 lb (10 kg) each — the largest screen size on this shelf — with stepless, tool-free spring adjustment and a target-weight indicator.
Best for: Two large or curved screens up to 35 in, on a desk shared between people who reposition them often.
A 17-piece set of dust plugs for unused PC interfaces rather than a full equipment cover — on a listing that names no port types and has no current US offer.
Best for: Closing the unused ports of a desktop PC or dock that sits in a dusty room.
A tailored linen dust cover sized for 20 to 22-inch monitors, protecting against dust, fingerprints, UV exposure and splashes, with a rear cable opening.
Best for: A 20 to 22 in monitor left unused for stretches — evenings, weekends, holidays — in a dusty or sunlit room.
A rotating spring-clamp hanger whose listing matches the Celerion hook point for point, and which reaches further down the thickness range — 0.31 in, about 8 mm, at the thin end.
Best for: A thin desktop or a glass top, where 8 mm (0.31 in) is the figure that decides it.
