Ergotron LX Sit-Stand Wall Mount LCD Arm Polished Aluminum
PRODUCT DESCRIPTION
Ergotron LX Sit-Stand Wall Mount LCD Arm Polished Aluminum (45-353-026) - 10 Years Local Warranty
Sit-Stand Monitor Positioning from the Wall — 20″ of Lift
The Ergotron LX Sit-Stand Wall Mount LCD Arm (45-353-026) gives a wall-mounted display 20″ (51 cm) of vertical travel — enough to move the same screen between a seated user and a standing one. That is the specific difference between this arm and the standard LX Wall Monitor Arm, which lifts 13″ (33 cm). Where a screen is shared across a shift, or where a clinician stands at one patient and sits at the next, the extra travel is what makes one mount serve both.
33″ of Reach, Folding Back to 4.5″
The arm extends 33″ (84 cm) from the wall to bring the display right to the user, then folds back to a depth of just 4.5″ (12 cm). In a Singapore consult room, nurses' station, reception counter or narrow office bay, that combination — long reach when working, near-flat when parked — is exactly what a fixed wall plate cannot provide.
Full Articulation for Displays up to 42″
Ergotron rates the arm for displays of 7–25 lbs (3.2–11.3 kg) at screen sizes up to 42″, with 75° of tilt (70° up / 5° down) and 360° of pan, so the screen angles precisely to the viewer's eye line at any working height.
Built for Shared, High-Traffic Workspaces
Because the arm mounts to the wall rather than the desk, the worktop below stays completely clear for paperwork, a laptop or clinical equipment. Theft-deterrent anchor holes accept a cable lock, which matters in shared, publicly accessible or unattended positions.
Ten-Year Ergotron Warranty, Supported Locally in Singapore
Ergotron backs the LX Sit-Stand Wall Mount LCD Arm with a 10-year manufacturer warranty. SourceIT Pte Ltd supplies it with local Singapore warranty support and a GST invoice.

Compatibility & Fit
VESA fit. Ergotron specifies this arm as VESA MIS-D / MIS-E / MIS-F, which spans the common business-monitor patterns. Ergotron does not publish the mm hole spacings for this model on its datasheet, so if your display uses an unusual pattern, confirm with SourceIT before ordering rather than assuming.
Weight and size fit. 7–25 lbs (3.2–11.3 kg), screens up to 42″. The 7 lb lower bound matters on a sit-stand arm: the counterbalance needs enough load to hold height smoothly, so a very light panel can drift.
Ultrawide and curved displays. Ergotron publishes the limit by weight and diagonal, not by aspect ratio. A 34″ or 38″ ultrawide within 25 lbs will mount. On a 33″-reach sit-stand arm, a wide panel places significant mass a long way from the wall plate, so the four-times-weight wall requirement below is not a formality — check the substrate properly.
Number of screens. Single display as supplied. Ergotron lists the Dual Monitor & Handle Kit (97-783) as an accessory for this arm — see the ordering section.
Sit-stand use. The 20″ (51 cm) of travel is the reason to choose this model over the standard LX Wall Monitor Arm. Set the arm's tension for your actual display weight at installation; that is what makes the height change effortless in daily use.
Wall type — important in Singapore. Ergotron requires the wall structure to support four times the total weight of the mounted equipment, and documents wood-stud and concrete fixing. Reinforced concrete and solid block walls, standard in most Singapore buildings, are suitable. A plasterboard partition without structural backing is not — particularly with a 33″ extended arm, where leverage on the fixing is at its greatest. SourceIT can advise on the mounting point.

Frequently Asked Questions — Ergotron LX Sit-Stand Wall Mount LCD Arm
What makes this a sit-stand arm rather than a standard wall arm?
The vertical travel. This arm lifts 20″ (51 cm); the standard LX Wall Monitor Arm lifts 13″ (33 cm). 20″ is enough to move a display between a seated eye line and a standing one, which is what lets one screen serve both postures.
What size and weight of monitor does it take?
Ergotron rates it for 7–25 lbs (3.2–11.3 kg) at screen sizes up to 42″. Use the panel weight excluding the factory stand.
Can it hold two monitors?
Not as supplied — it is a single-display arm. Ergotron lists the Dual Monitor & Handle Kit (97-783) as an accessory for this model if you need to add a second screen.
Is there a version with a keyboard tray and CPU holder?
Yes. The LX Sit-Stand Wall Mount System (45-358-026) bundles the sit-stand LCD arm with a sit-stand keyboard arm, a medium CPU holder and a wall track on one integrated wall system. If you only need the keyboard half, the LX Sit-Stand Wall Mount Keyboard Arm (45-354-026) is sold separately.
What wall can it be fitted to, and how far does it stick out?
The wall structure must support four times the total mounted weight; Ergotron documents wood-stud and concrete fixing. Concrete and solid block are suitable, plasterboard partitions are not without backing. The arm reaches 33″ (84 cm) when extended and folds back to 4.5″ (12 cm) when parked.
Do I need a VESA adapter?
The arm is specified as VESA MIS-D / MIS-E / MIS-F, which covers most business monitors. Ergotron does not publish the mm spacings for this model, so confirm with SourceIT if your display uses an unusual pattern or has no VESA holes at all.
Can it be secured against theft?
Yes — Ergotron builds in theft-deterrent anchor holes that accept a cable lock, which is worth using in reception, ward and other publicly accessible positions.
Is the Ergotron LX Sit-Stand Wall Mount LCD Arm covered by warranty in Singapore?
Yes. Every Ergotron LX Sit-Stand Wall Mount LCD Arm sold by SourceIT comes with local Singapore warranty and a GST invoice; Ergotron backs the LX Sit-Stand Wall Mount LCD Arm with a 10-year manufacturer warranty.
