Animation for Ergotron 45-354-026 LX Sit-Stand Wall Mount Keyboard Arm


Ergotron 45-354-026 is a sit-stand wall mounting keyboard tray that is ideal for high-traffic, public spaces. Combine it with a wall mounting monitor arm and you have a complete ergonomic set-up.

Effortlessly position a keyboard to the most comfortable typing position, while seated or standing. The LX provides a very stable platform for a keyboard and mouse - tested to be 3x more rigid than other keyboard arms. The tray’s side-to-side adjustment mechanism allows the surface to be parallel, no matter where the keyboard is positioned, while its fore-aft back-tilt angle keeps hands and wrists in a comfortable, ergonomic position.

Frequently Asked Questions

q The animation for this product shows the mouse on left and right. My question is can the mouse pad be extended on both sides at the same time? I intend to use this for a personal office space and I have a "command pad" which sits to the left of my keyboard almost like a left-handed mouse.

The mouse tray travels on the underside of the keyboard tray- it is either pulled out on the right or left, it cannot be pulled out on both sides at the same time.

q I'm interested in buying six of your Ergotron 45-354-026 LX Sit-Stand Wall Mount Keyboard Arms. I'd like to know if the mounting kit is included in the price or is it something that I'd need to buy separately.

The wall mount base is included in the package, and with this base you can attach the arm directly to sturdy vertical surfaces. If you are interested in attaching the arm to a wall plate for extra support, or if you consider the wall track (Option 1) for more vertical adjustment, then you would need to order those separately.

q Can the keyboard of the Ergotron 45-354-026 LX Sit-Stand Wall Mount Keyboard Arm sit flat on a desk surface?

This keyboard arm cannot sit flat on a desk surface. It is meant for the wall and possibly to be combined with a wall mounting monitor arm to create a complete workstation. The 45-354-026 folds up 90° in order to be able to stow away flat and has 5° of negative tilt (where the f keys would be tilted downward and space key would be tilted upward) in order to discourage carpal tunnel.

Keyboard arm - stable, I was surprised

by ERIC S, Massachusetts, May 03, 2018

I was initially skeptical that the arm would stay up while I hammer away, but stay it does. I have a big, fat ergonomic keyboard with number pad that sits well on the table. I have a big ergonomic wireless mouse, too. The mousing pad is a touch small but still does well. I wish there was a bit more room for a wrist pad. When I paired this with a monitor arm, I have a lot of mobility options that are great when working with other people or using my computer for atypical things like reading music while playing guitar, etc.

Great Product - One 'manageable' design flaw

by Michael B, Maryland, Mar 15, 2016

This is the perfect product for me, and I'm sure I'll be back to buy similar products for Monitors/Laptops. However, this product is not level enough to keep the mouse from sliding off the back of the tray, and I was not able to locate an adjustment to level it. There are four screws that anchor the keyboard tray to the arm. I used rubber washers (several) on the two upper screws to slightly pitch the angle forward, and this worked well enough to live with; even though it isn't perfect.
