The WorkFit-TL and WorkFit-T Both Fit a 24 Inch Desk, and Both Rise Straight Up
Two converters off one spec sheet, both 23 in deep, and both stated to rise straight up.
The numbers
- WorkFit-TL worksurface: 37.5 x 23 in, tray 27.5 x 11 in
- WorkFit-T worksurface: 35 x 23 in, tray 24.75 x 9.25 in
- Lift: 15 in on both
- Capacity: 10 to 40 lb on the TL, 10 to 35 lb on the T
- They weigh 62 lb and 58.5 lb
- Desk needed: 24 in deep or larger, no clamping
- Keyboard sits 4.5 in below the worksurface and moves with it
- Warranty: five years on the sheet, and neither model is in the warranty document
Verdict
Worth it if you want the two facts a corner-desk owner actually needs, in print. These are the only converters here that publish a 24 in minimum surface depth and a written promise that the platform travels straight up. The WorkFit-TX, which Ergotron rates for corners, publishes neither.
The standards failure I gave these originally does not stand. Ergotron has no products in the BIFMA Compliant register at all, so there was never a listing to be missing from.
The warranty is what stays thin. Ergotron’s March 2026 document names neither model. Get the term from whoever invoices you.
The difference between them is 2.5 inches and 5 pounds
Both come off the same Ergotron product sheet. The TL is 37.5 in wide, the T is 35, they are both 23 in deep, and they both lift 15 in. The TL takes 40 lb and the T takes 35. The TL’s keyboard tray is 27.5 by 11 in, the T’s is 24.75 by 9.25.
That is the whole difference. If you are choosing between them on paper, the tray is the part you will notice daily, because 11 in of depth takes a keyboard and a mouse side by side and 9.25 in makes you choose.
Twenty-three inches deep is the number that makes these two work in a corner. Ergotron asks for a surface “24 in deep or larger” and then leaves you an inch of margin, which sounds tight until you compare it to the WorkFit-TX sitting 27 in deep with no stated minimum at all.
Straight up, and Ergotron says so in writing
The counterbalance uses what Ergotron calls Constant Force technology, and the sheet is unusually direct about what that means in space terms. The system “lifts straight up and down to minimize intrusion into the workspace”, and the platforms “move straight up and down, always staying within the footprint”.
In an open office that reads as a nice-to-have. In a nook it decides whether the thing is usable, because a platform that arcs forward as it rises needs clearance in front of the desk, and a corner is the one place you have none.
The keyboard tray moves with the worksurface rather than separately, sitting 4.5 in below it throughout the travel. That is a simpler arrangement than the TX’s independently adjustable tray, and whether you want simple or adjustable depends on how close your seated and standing elbow heights are.
Ergotron has quietly stopped listing the WorkFit-T
The comparison chart on Ergotron’s site rates the WorkFit-TL “Yes” for a corner workspace, alongside the TX and the Z Mini. The WorkFit-T is not on that chart. It is not rated Limited or No either. It is simply not there.
It is still on the August 2025 product sheet, its product page still loads, and Ergotron has published nothing to say it is going away. Read that how you like. If you want the model the company is still actively grading and comparing, that is the TL.
The five years lives on a sales sheet
Both models carry a five-year warranty according to the product sheet. Ergotron’s actual warranty document, updated March 2026, lists the WorkFit-Z Mini at two years, the WorkFit Elevate at ten, and the WorkFit-C and TeachWell desks at five. The T and the TL are not named in it, and neither is the TX.
Certification is thinner still. Ergotron holds BIFMA level 2 as a company and does not name the WorkFit converters in that claim. No GREENGUARD, no UL, no product-level BIFMA. One TL part number, 33-418-085, carries TAA compliance, which matters if you are buying on a US federal contract and not otherwise.
What is wrong with them
Drawbacks
Neither model appears in Ergotron’s warranty document. Source: manufacturer documentation. The five-year term is on a product sheet only.
No product-level certification. Source: what the manufacturer declines to state. BIFMA level 2 is a company claim that does not name these units.
The resting height is not published. Source: what the manufacturer declines to state. Neither model has a stated collapsed height above the desk, so how much of your surface it eats when you sit is unknown until it arrives.
Nobody says whether the 35 or 40 lb includes the keyboard tray. Source: what the manufacturer declines to state. If it does, a heavy keyboard is coming out of your monitor budget.
They are heavy. Source: manufacturer documentation. 62 lb on the TL and 58.5 on the T, arriving fully assembled, which is convenient once it is on the desk and awkward getting it there.
No published price. Source: availability. Ergotron closed its own store and publishes only a relative price tier.
Who it fits
Buy the TL if your desk leg is 24 in deep or more and you want the best-documented converter for a corner. The 23 in depth fits, the straight-up travel is stated rather than assumed, and the 11 in tray takes a keyboard and mouse without argument.
Buy the T if you find one cheap and 35 lb is enough. It is the same machine 2.5 in narrower with a smaller tray, and Ergotron has stopped listing it, which usually shows up in the price before it shows up anywhere else.
Skip both if your desk is under 24 in deep. Nothing in this range is rated for that, and the depth minimums across the category all start at the same place.
Questions people ask
What is the difference between the WorkFit-T and the WorkFit-TL?
The TL is 2.5 in wider at 37.5 in, takes 40 lb instead of 35, and has a larger keyboard tray at 27.5 by 11 in against 24.75 by 9.25. Depth, lift and mechanism are identical.
How deep does my desk need to be?
24 in or larger, per Ergotron, for both models. No clamping or mounting is required.
Does the WorkFit-TL work on a corner desk?
Ergotron rates it Yes for corner workspaces. At 23 in deep it clears a 24 in desk leg with an inch to spare.
Does the platform move straight up?
Yes. Ergotron states that both models lift straight up and down and stay within their own footprint.
How high do they lift?
15 in on both.
Is the WorkFit-T discontinued?
Ergotron has published no discontinuation notice, and the model is still on the current product sheet with a live product page. It has been dropped from the comparison chart the other converters appear on.
What is the warranty?
Five years, stated on the product sheet. Ergotron’s warranty document names neither model.
