Ergotron WorkFit Models, Compared

The load-rating column is not one measurement. On the tabletop units it is what you put on the surface, and Ergotron does not state whether the monitor counts. On the two dual WorkFit-S configurations, 33-349-200 and 33-341-200, and on the WorkFit-A and the WorkFit-C, it is a total on the height-adjustment assembly, with the display explicitly inside the figure.

Reading 40 lb against 20 lb is comparing two different things.

Dimensions, lift figures, capacities and warranties are Ergotron’s published specs.

How Each Ergotron WorkFit Attaches

Tabletop: the WorkFit-T, the TL, the TX and the Corner. Each sits on top of the desktop, and each needs a desk 24 inches deep or larger.

Front clamp: the WorkFit-S. It grips the front edge of the desk, so the desk needs a free front edge and nothing sits on the desktop. On 33-349-200 that edge has to be 0.47 to 2.4 inches thick.

Desk arm: the WorkFit-A. Two routes onto the desk. A desk clamp that works with desks up to 31.5 inches deep, or a grommet mount through a hole 0.5 to 2.5 inches wide with its center no more than 29.5 inches from the front edge. A grommet is the cable hole cut through a desktop.

Rolling cart: the WorkFit-C. Four dual casters, two of them locking. It attaches to nothing and needs no desk.

Whole desk: the WorkFit-D. Four leveling glides, and a worksurface that runs from 30.6 to 50.6 inches off the floor.

Can You Buy a WorkFit Straight From Ergotron?

Yes, for all but three of the ten in the table. The WorkFit-C, the WorkFit-D and the WorkFit Corner are quote only on Ergotron’s site, with Request a Quote in place of a price.

Same lift as the TL, less moneyErgotron WorkFit-T: The Same 15 Inch Lift as the TL, for Less

The WorkFit to buy when the desk is at least 24 inches deep and the price decides it: the same 15 inch lift as the TL, on a worksurface 2.5 inches narrower.

• Ergotron about $550 to $575

Measure your keyboard before you order. The tray is 25 by 9 inches, and Ergotron recommends a maximum keyboard width of 18 inches for it.

The screen sits on the worksurface. Ergotron gives a maximum screen size of 30 inches and sells a separate monitor mount kit, because there is no arm on the unit.

More worksurface, same liftErgotron WorkFit-TL: A Wider Worksurface on the Same 15 Inch Lift

Buy it over the WorkFit-T for the wider worksurface, the bigger tray and 5 lb more capacity. The lift and the desk depth are identical.

• Ergotron about $575 to $600

The keyboard tray sits 4.5 inches below the worksurface and moves in tandem with it, so the two go up and down together.

The screen goes on the worksurface here too, up to 30 inches, with a separate mount kit if you want it off the surface.

One SKU to skip unless a contract makes you buy it. Part 33-418-085 is the same TL hardware sold as TAA compliant and USA assembled, in the $1,350 to $1,400 band at Ergotron. It matters only if a federal procurement rule requires it.

More lift than the T, TL or CornerErgotron WorkFit-TX: 20 Inches of Lift

• Ergotron about $800 to $850

The WorkFit-TX worksurface is 32 by 27 inches. The TL’s is 37.5 by 23. The TX is narrower and deeper.

The WorkFit-T, the WorkFit-TL and the WorkFit Corner each lift 15 inches. The TX lifts 20. The worksurface and keyboard tray rise 17 inches together, then the tray moves a further 3 inches on its own.

Like the T and the TL, it fits a desk 24 inches deep. It’s the one to pick if you want the keyboard and the screen at their own heights, because the tray can move without the screen.

Two monitors on a clampErgotron WorkFit-S: The Front-Clamp Pedestal, in Three Configurations

The one to buy when the desktop is full and the desk has a clear front edge. Start with the dual that has no worksurface, $725 to $750 at Ergotron, and add the worksurface later if you want it.

• Ergotron, dual with worksurface, 33-349-200 about $925 to $950
• Ergotron, single LD with worksurface, 33-350-200 about $800 to $850
• Ergotron, dual with no worksurface, 33-341-200 about $725 to $750

A front clamp grips the desk edge, so the footprint on the desktop is zero. On 33-349-200 the clamp takes an edge 0.47 to 2.4 inches thick. Measure the front edge before anything else, because an edge outside that range rules that model out.

The dual with a worksurface, 33-349-200, takes two monitors and includes the worksurface. The single LD, 33-350-200, takes one monitor and has a 23 by 15 inch worksurface and a 27 by 9 inch keyboard tray. The dual with no worksurface, 33-341-200, ships with a keyboard tray and a mouse tray and no worksurface panel at all.

Read the capacity figure twice. On 33-349-200 the rating is 25 lb total on the height-adjustment assembly, and Ergotron breaks it out: 6 to 12 lb for each screen, up to 5 lb for the worksurface, up to 5 lb for the keyboard tray. The display is inside that number.

On 33-341-200 the total is 31 lb, split as 6 to 14 lb per screen plus up to 5 lb of keyboard tray. That is not the measurement a tabletop unit publishes, and the bigger number is not the stronger unit.

Monitors mount to VESA MIS-D on all three. The two dual models rotate 360 degrees and take two screens up to 24 inches, and Ergotron notes the mount accommodates some 26 inch screens at up to 24.5 inches of outside width. The single LD adds 30 degrees of tilt and takes a screen up to 27 inches.

The desk armErgotron WorkFit-A: The Desk Arm, on a Clamp or Through a Grommet Hole

The one to buy when you want the screen on an arm rather than on a platform, and the desk has a grommet hole or a clampable edge.

• Ergotron, 24-390-026 about $700 to $725

Check the grommet dimensions before ordering. The grommet mount takes a through-hole 0.5 to 2.5 inches wide, and the center of that hole has to sit no more than 29.5 inches from the front edge of the desk. The clamp route works with desks up to 31.5 inches deep.

Mounting it through a grommet hole is handy when the desk edge is already taken.

Move it room to roomErgotron WorkFit-C: A Rolling Cart, Not a Desk Converter

Buy it to move a workstation between rooms. If it’s going to live in one spot next to a desk, a WorkFit-S holds more.

• Ergotron Request a Quote, no listed price

It is a freestanding cart with its own base. Nothing clamps, nothing sits on a desktop, and the desk depth question does not arise.

No desk to put it onErgotron WorkFit-D: A Whole Standing Desk, Not a Converter

Buy it when there is no desk to convert. It’s a desk with 20 inches of travel built into the legs.

• Ergotron Request a Quote, no listed price

The 165 lb rating is the load on the desk’s own worksurface, not on a platform sitting on a desk.

The WorkFit-D publishes absolute heights, 30.6 inches to 50.6 inches off the floor, so you can check it against your own elbow height. The WorkFit-T, the WorkFit-TL, the WorkFit-TX and the WorkFit-S dual with worksurface publish travel instead. None of those four pages says whether the travel starts at the desk surface or at the base of the unit.

Shaped for a corner deskErgotron WorkFit Corner: The Tabletop Unit Shaped for a 90 Degree Desk

• Ergotron Request a Quote, no listed price

The WorkFit Corner is part 33-468-921, a tabletop unit with a notched worksurface shaped to hug a 90 degree corner desk or a cube wall.

Ergotron publishes no worksurface footprint for the Corner. That is the measurement a corner buyer needs. Ergotron’s own copy says the Corner “has more worksurface and the largest keyboard platform of any WorkFit converter,” which is the brand’s claim with no figure behind it.

What Did Not Make the Cut

Fourteen WorkFit part numbers were read on Ergotron’s own store. Ten are in the table above. Four are not:

• WorkFit-Z Mini, 33-458-917. A tabletop converter in the $350 to $375 band on Ergotron’s own store, with Add to Cart shown. It holds 25 lb, and that ceiling is what keeps it out of the table: the WorkFit-T and the WorkFit Corner hold 35 lb, and the WorkFit-TL and the WorkFit-TX hold 40 lb. Its keyboard tray is 24.5 by 9.1 inches and it ships assembled. It fits a desk 22 inches deep, where the T, the TL, the TX and the Corner each need 24 inches, so it is the one to look at when the desk is shallower than that.
• WorkFit-SR, 33-407-085. A rear clamp rather than a front clamp, so it attaches at the back of the desk instead of the front. It publishes 23 inches of monitor height adjustment. At $1,650 to $1,700 on Ergotron’s store, it costs more than twice the WorkFit-S dual with no worksurface, so it’s worth it only if the front of your desk can’t take a clamp.
• WorkFit-TLE, 33-444-921. Ergotron’s product page carries a discontinued banner, with no price and no Add to Cart.
• WorkFit-TL TAA, 33-418-085. The same TL hardware under a compliance SKU, in the $1,350 to $1,400 band at Ergotron. It is covered in the WorkFit-TL section rather than given a row of its own.

How to Choose an Ergotron WorkFit

1. Measure the desk depth first. The WorkFit-T, the WorkFit-TL, the WorkFit-TX and the WorkFit Corner each need a surface 24 inches deep or larger. The WorkFit-Z Mini publishes 22 inches.
2. Then decide what the unit grabs. A free front edge takes a WorkFit-S, and on 33-349-200 that edge has to be 0.47 to 2.4 inches thick. A grommet hole within 29.5 inches of the front edge, or a desk up to 31.5 inches deep, takes a WorkFit-A. The WorkFit-T, the TL, the TX and the Corner sit on the desktop instead, on a surface at least 24 inches deep.
3. Check whether the capacity number includes the screen. This is the one that catches people. Look for the words “total load on the height-adjustment assembly” on any listing before you compare two capacity figures.
4. Check whether there is a monitor mount at all. Tilt, pan, rotation and VESA read as a dash on the WorkFit-T, WorkFit-TL and WorkFit-TX spec panels, which means the screen sits on the surface or needs an accessory kit. The WorkFit-S, A and C are VESA MIS-D.
5. Warranty will not decide it. Ergotron publishes five years on the WorkFit-T, TL and TX, all three WorkFit-S configurations, the WorkFit-A, the WorkFit-C and the WorkFit-D.

Where to go next

I sold contract-grade furniture from 2016. Corner Nook now covers furniture for small spaces, corners, nooks, and rooms that have to do two jobs. More about who runs it. The prices, stock, ratings, shipping and returns here were checked against Ergotron’s own product pages at the time of writing.
