A vertical pair on a deep desk
Nothing is sold on this site. Every buying link opens the same item at the retail partner who handles payment, delivery and returns.
The second stacked layout in the range, rated slightly wider at 13 to 33 inches and 19.8 lbs per screen. Stacking is the layout for desks with depth but not width, and for work where one screen is being watched and the other worked on. Mounting is by clamp on a single post, so the desk footprint is a single clamp jaw regardless of how many screens are on it.
A stacked pair is easiest to build from the top down in terms of planning and from the bottom up in terms of execution: decide the top screen height first while standing at the desk, then fit the lower screen, then the upper. Fitting the upper one first leaves no room to work under it.

Figures as published for this model. Anything that has never been published is left out rather than estimated.
The same figures as every other page in this section, lined up against the section itself. Being the biggest at something is not the same as being the best at it, so the last column says where a number puts this model and leaves the judgement to you.
| Figure | This model | All 18 mounts | Where that puts it |
|---|---|---|---|
| Largest screen it takes | 33 in | 27 to 49 in | Bigger than 10 of the other 17 |
| Smallest screen it takes | 13 in | 13 to 17 in | The smallest of the 18 |
| Weight per arm | 19.8 lb | 17.6 to 37.4 lb | Stronger than 7 of the other 17 |
| Screens carried | 2 | 1 to 3 | More than 6 of the other 17 |
Ranges cover only the mounts that publish the figure at all; a model that has never published one is left out of that row rather than counted as a zero.
Of the 18 mounts in this section this is the eleventh cheapest: 10 cost less, 7 cost more, and the section runs from $19.98 to $89.99. It carries a published list price of $69.99, so the figure above is below that rather than the usual asking price.
There is no figure here on which it beats everything cheaper in the section, so if none of the 10 below it is missing something you need, the difference is colour, top size or finish rather than capability.
It carries 6,307 customer reviews at 4.5 out of five, which is the highest rating in the section. Those numbers come from the retail listing and are reproduced rather than curated, including when they are unflattering.
The product description exactly as it ships with the listing, unedited, so everything written above can be checked against it.
