3M Adjustable Keyboard Tray AKT90LE vs HUANUO Under Desk Keyboard Tray for Flat Bottom and Cross Beam Desks
Which should you buy? Our verdict on both, pulled from our full The Best Under-Desk Keyboard Trays: 4 Compared (and One to Skip) comparison.
The 3M AKT90LE pairs a repeatable lift-and-lock arm with 15 degrees of negative tilt, a stiff wood platform, and a 23 inch track that hides the whole assembly, and its warranty outlasts most desks. The HUANUO is the pick when a standing desk cross beam blocks everything else, trading a little platform depth for bracket hardware that actually mounts and a steeper 22 degree tilt.
3M Adjustable Keyboard Tray AKT90LE
Buy itThe reference under-desk tray: a lift-to-set arm with printed height and tilt scales, 15 degrees of negative tilt, and a 23 inch track that swallows it whole.
- Tilt runs 10 degrees up to 15 degrees down, with a printed scale so you can find a position again
- Height adjusts roughly 4.5 inches above to 6 inches below the mounting surface by lifting the front edge
- Wood platform at 25.5 by 12 inches resists the bounce that plagues thin plastic trays
- 23 inch track lets the tray stow completely under the desk, and the platform swivels 360 degrees
- Needs about 23 inches of unobstructed depth under the desk, which rules out shallow desks and most cross-beam standing desk frames
- Assembly instructions draw steady criticism for being vague, and the install is a genuine project
HUANUO Under Desk Keyboard Tray for Flat Bottom and Cross Beam Desks
Buy itThe tray that mounts to a standing desk frame, with bracket hardware for cross beams and more negative tilt than anything else here.
- Includes two brackets that bridge a cross beam up to 2 inches tall, so electric standing desks are no longer a dealbreaker
- Tilt goes 6 degrees up to 22 degrees down, the steepest negative angle in this group
- 6.3 inches of height travel plus 180 degrees of swivel covers both seated and standing positions
- Metal roller slide rated by the manufacturer for 20,000 cycles, and early owner reports back the build quality
- Fit rules are strict: desktop deeper than 17 inches, thicker than 0.6 inches, wood or particle board only, and 35 inches of clear width for full swivel
- The 25 by 9.84 inch platform is shallower than the 3M board, so a keyboard with a bulky wrist rest plus a mouse gets tight
- Recent listing, so the long-term owner record is still thin and reports split on how smoothly the slide runs
