Ergotron LX Sit-Stand Wall Keyboard Arm
PRODUCT DESCRIPTION
Ergotron LX Sit-Stand Wall Keyboard Arm (45-354-026) - 10 Years Local Warranty
Wall-Mounted Sit-Stand Typing — 20″ of Height Adjustment
The Ergotron LX Sit-Stand Wall Mount Keyboard Arm (45-354-026) puts a keyboard and mouse on the wall and gives them 20″ (51 cm) of vertical travel — enough to move the typing surface between a seated height and a standing one. That extra travel is the single difference that matters against the standard LX Wall Mount Keyboard Arm, which lifts 13″ (33 cm). Where a workstation is shared across a shift, or a user alternates between sitting and standing through the day, this is the arm that supports both without compromise.
42″ of Reach, Folding Back to 5.8″
The arm brings the keyboard 42″ (107 cm) out from the wall so the user can stand comfortably clear of it, then folds back to 5.8″ (15 cm) when parked. In Singapore clinical bays, laboratories, industrial workstations and point-of-care positions where a permanent desk is impractical but ergonomic typing is still required, that reach-then-retract behaviour is what a fixed shelf cannot deliver.
Constant Force™ Technology — Effortless, Tool-Free Movement
Ergotron's patented Constant Force™ Technology is what makes the arm move under fingertip pressure and stay exactly where it is set. There are no knobs to loosen and re-tighten between users, which is precisely what determines whether a shared height-adjustable workstation actually gets adjusted in practice or quietly gets left at one setting.
Back-Tilt Keyboard Position and 360° Pan
The tray back-tilts 5° in the down position — the negative-tilt geometry that keeps wrists neutral during sustained typing — and folds 90° upright for storage. A full 360° of pan lets the keyboard swing to whichever side of the wall point the user is standing on. Ergotron rates the arm for keyboards up to 17.6″ × 9.5″ (44.6 × 24 cm) and a load of 5 lbs (2.3 kg).
Ten-Year Ergotron Warranty, Supported Locally in Singapore
Ergotron backs the LX Sit-Stand Wall Mount Keyboard Arm with a 10-year manufacturer warranty. SourceIT Pte Ltd supplies it with local Singapore warranty support and a GST invoice.

Compatibility & Fit
Keyboard fit. Ergotron rates the tray for keyboards up to 17.6″ × 9.5″ (44.6 × 24 cm). That comfortably covers a standard full-size keyboard with a number pad, and every tenkeyless or compact board. An oversized gaming or split ergonomic keyboard should be measured against those figures before ordering. Ergotron publishes the maximum keyboard size but not the tray's own outer dimensions, so SourceIT does not quote a tray measurement here.
Weight. The rated load is 5 lbs (2.3 kg), covering a keyboard and mouse. It is not a shelf — do not rest a laptop, tablet or documents on it.
Mouse. A wall-mounted mouse holder is included, so the mouse is carried by the installation rather than needing a separate surface.
Monitor mounting is separate. This is a keyboard arm only — no display mount, no VESA plate. To put a screen on the same wall, pair it with the matching Ergotron monitor arm, or specify one of the complete LX Wall Mount Systems that bundles arm, keyboard and CPU holder on a single wall track. Both routes are listed in the ordering section below.
Which of the two keyboard arms. This sit-stand model lifts 20″ (51 cm) and reaches 42″ (107 cm); the standard 45-246-026 lifts 13″ (33 cm) and reaches 35″ (89 cm). Choose this one if a standing user must be supported; choose the standard arm if all use is seated and you want a lower folded depth (3.5″ against 5.8″).
Wall type — important in Singapore. Ergotron's instruction is to attach directly to a sturdy vertical surface and to install into a wood stud where applicable; for concrete, anchors must be set at least 3-1/8″ (80 mm) deep in solid concrete, not into mortar. The wall structure must support four times the total weight of the mounted equipment. Reinforced concrete and solid block walls — standard in most Singapore commercial buildings, HDB flats and condominiums — are suitable. A plasterboard partition without a backing stud is not. SourceIT can advise on the mounting point before you order.
Wall Track option. The arm can also be fitted to an Ergotron Wall Track using bracket 97-091, which is ordered separately. Wall Track lets you slide the arm's position along the track later without re-drilling — worth specifying if the workstation layout is likely to change.

Frequently Asked Questions — Ergotron LX Sit-Stand Wall Mount Keyboard Arm
What is the difference between the LX Wall Mount Keyboard Arm and the LX Sit-Stand Wall Mount Keyboard Arm?
Travel and reach. 45-246-026 lifts 13″ (33 cm), reaches 35″ (89 cm) and folds to 3.5″ (9 cm). 45-354-026 lifts 20″ (51 cm), reaches 42″ (107 cm) and folds to 5.8″ (15 cm). Keyboard capacity (5 lbs), maximum keyboard size, tilt, 360° pan, Constant Force™ motion and the 10-year warranty are identical — both share one Ergotron datasheet. See the LX Wall Mount Keyboard Arm.
What size keyboard fits?
Up to 17.6″ × 9.5″ (44.6 × 24 cm), which covers full-size boards with a number pad. Measure an oversized or split ergonomic keyboard against those figures first.
Does it come with a mouse tray?
A wall-mounted mouse holder is included with the arm.
Can I mount a monitor on it too?
Not on this arm — it carries a keyboard only. Pair it with an Ergotron wall monitor arm, or specify a complete LX Wall Mount System that puts monitor, keyboard and CPU holder on one wall track. Both options are listed in the ordering section above.
What wall can it be fitted to?
A sturdy vertical surface: a wood stud where applicable, or solid concrete with anchors at least 3-1/8″ (80 mm) deep. The wall must support four times the total mounted weight. Concrete and solid block, standard in Singapore, are suitable; plasterboard partitions are not without backing.
Can I move the arm later without re-drilling the wall?
Yes, if you mount it to an Ergotron Wall Track using bracket 97-091 — both ordered separately. The arm then slides along the track to a new position. Fixed directly to the wall, relocating means re-drilling.
Is it suitable for a standing workstation?
The sit-stand model (45-354-026) is designed for it, with 20″ (51 cm) of travel. The standard model (45-246-026), at 13″ (33 cm), is intended for seated work and modest height variation between users.
Is the Ergotron LX Sit-Stand Wall Mount Keyboard Arm covered by warranty in Singapore?
Yes. Every Ergotron LX Sit-Stand Wall Mount Keyboard Arm sold by SourceIT comes with local Singapore warranty and a GST invoice; Ergotron backs the LX Sit-Stand Wall Mount Keyboard Arm with a 10-year manufacturer warranty.
