Ergotron LX Sit-Stand Wall Mount System, Medium CPU Holder
PRODUCT DESCRIPTION
Ergotron LX Sit-Stand Wall Mount System, Medium CPU Holder (45-358-026) - 10 Years Local Warranty
A Complete Sit-Stand Workstation on a Single Wall Track
The Ergotron LX Sit-Stand Wall Mount System (45-358-026) puts a monitor arm, a keyboard arm and a medium CPU holder on one wall track, turning a bare wall into a full workstation with no desk and no floor footprint. Both arms carry 20″ (50.8 cm) of independent height adjustment, so the display and the keyboard each move between seated and standing positions — which is what genuinely enables sit-stand working, rather than a screen that rises while the keyboard stays put.
Long Reach, Then Folds Back Within Inches of the Wall
The monitor arm extends 32.8″ (832 mm) and the keyboard arm 42″ (1,068 mm), bringing both to a standing user well clear of the wall. When the shift ends, the keyboard folds to within 6.8″ (17.3 cm) of the wall and the monitor arm back to 5.5″ (14 cm). In a Singapore ward corridor, consult room or narrow clinical bay, an entire workstation that disappears against the wall between users is the difference between a compliant installation and an obstruction.
Effortless Independent Lift, Tilt and Pan
Ergotron's design gives multiple points of adjustment on both arms, so lift, tilt and pan of the display and the keyboard tray happen without tools and without asking the next user to fight a stiff joint. The back-tilt keyboard tray protects wrists from the strain of typing on a flat or positively angled surface — a small geometric detail that carries most of the ergonomic benefit in sustained data-entry work.
Integrated CPU Holder and Cable Management
The medium CPU holder (silver) keeps the computer secured and off the floor, protected from dust, cleaning trolleys and accidental knocks, and travels with the rest of the system on the same track. Integrated cable management and cable channels organise and route cords out of sight, so the finished installation reads as engineered rather than assembled.
Tested to 10,000 Cycles and Backed for Ten Years
Ergotron states the system is built for thousands of movements, having passed a 10,000-cycle test, and backs it with a 10-year manufacturer warranty. For a shared workstation that will be readjusted several times a day for a decade, cycle life is the specification that matters most. SourceIT Pte Ltd supplies the system with local Singapore warranty support and a GST invoice.

Compatibility & Fit
VESA fit. Ergotron's datasheet does not publish a VESA figure for this part number — it refers to the Ergotron website for detail. SourceIT will not state a pattern we cannot verify from the datasheet. Send us your monitor model and we will confirm the fit with Ergotron before you order.
Display weight and size. Ergotron rates the display arm at ≤ 7–25 lbs (3.2–11.3 kg) for screens up to 42″. Note Ergotron's own caveat: a monitor deeper than 2.5″ (64 mm) may reduce the usable capacity, so a thick or deeply curved panel should be checked against its actual weight rather than the headline figure.
Ultrawide and curved displays. The published limit is weight and diagonal, not aspect ratio. An ultrawide within the weight ceiling and carrying a supported VESA pattern will mount, but a wide panel on an extended arm loads the wall track asymmetrically — centre it carefully and set the arm tension for the real display weight at installation.
Number of screens. One display. This system is not a dual-monitor solution.
Keyboard fit. The tray is rated 0–5 lbs (0–2.3 kg) — a keyboard and mouse, not a laptop or a stack of files. Ergotron does not publish the tray's outer dimensions for this part number, so SourceIT does not quote one.
CPU / computer fit. The bundled medium CPU holder (silver) accepts computers 2–8″ (5–20 cm) wide; includes a plastic spacer to accommodate most small form factor and ultra-small form factor CPUs. That covers most small-form-factor and ultra-small-form-factor desktops. Measure your chassis width against that range before ordering.
A note on CPU holder capacity. Ergotron's dimensional drawings print two weight figures against the small and medium CPU holders, but the two published documents do not agree on which figure belongs to which holder. SourceIT therefore does not quote a CPU holder weight capacity rather than publish a figure we cannot verify. The size ranges below are confirmed by Ergotron's datasheet text. If CPU weight is critical to your specification, contact SourceIT and we will confirm with Ergotron.
Wall type and wall track — important in Singapore. The system mounts on a single Ergotron Wall Track 34″ (864 mm) long, with mounting holes at 8″ (203 mm) intervals. Ergotron's installation guide specifies two substrates: solid concrete, drilled Ø 3/8″ (10 mm), and a wood stud, drilled Ø 3/16″ (5 mm). Stud fixing uses M8 × 80 mm or 5/16″ × 3″ bolts with flat washers in two places; the arms then attach to the track with #10-24 × 5/8″ button-head cap screws in four places. Reinforced concrete and solid block walls, standard across Singapore commercial buildings, HDB flats and condominiums, suit the concrete method. A plasterboard partition without structural backing is not a suitable substrate for a system of this weight. SourceIT can advise on the mounting point before you order.
Reconfigurable after installation. Because both arms clamp to the wall track rather than directly to the wall, you can loosen the screws and slide an arm to a new height or position without drilling again — useful where the same bay is used by different people or the layout is still settling.

Frequently Asked Questions — Ergotron LX Sit-Stand Wall Mount System
What is the difference between the versions of the LX Wall Mount System?
The CPU holder and the amount of height adjustment. 45-247-026 (medium CPU holder, silver) and 45-253-026 (small CPU holder, black) are identical apart from the bundled holder. 45-551-216 is the white finish and ships with no CPU holder at all. 45-358-026 is the sit-stand version: both its arms lift 20″ (50.8 cm) instead of 13″ (33 cm) and reach further. All four carry the same 10-year warranty.
What size and weight of monitor does it take?
Ergotron rates the display arm at ≤ 7–25 lbs (3.2–11.3 kg) for screens up to 42″. A monitor deeper than 2.5″ (64 mm) may reduce the usable capacity.
Can it hold two monitors?
No — the system carries one display, one keyboard tray and one CPU holder. It is not a dual-monitor solution.
Does it include a worksurface or shelf?
No. None of the LX Wall Mount Systems includes a worksurface — the keyboard arm carries a keyboard tray only. If you need a writing surface at the wall, that is a different Ergotron product family; contact SourceIT and we will specify it.
What wall can it be fitted to, and can I move the arms later?
Ergotron approves solid concrete (Ø 3/8″ / 10 mm holes) or a wood stud (Ø 3/16″ / 5 mm), fixed with M8 × 80 mm or 5/16″ × 3″ bolts. Concrete and solid block are standard in Singapore and suit the system; plasterboard partitions do not, without structural backing. Because both arms clamp to the 34″ wall track, you can loosen the screws and slide an arm to a new position later without drilling the wall again.
Do I need a VESA adapter?
Ergotron's datasheet does not publish a VESA figure for this part number — it refers to the Ergotron website for detail. SourceIT will not state a pattern we cannot verify from the datasheet. Send us your monitor model and we will confirm the fit with Ergotron before you order. A display with no VESA holes at all — some all-in-ones and consumer TVs — needs its manufacturer's own adapter plate, which is not supplied.
Is this suitable for sit-stand working?
Yes — this is the sit-stand model. Both the monitor arm and the keyboard arm travel 20″ (50.8 cm), so the whole workstation moves between seated and standing heights together.
Can I buy just the monitor arm or just the keyboard arm?
Yes. The individual components are stocked separately — see the component table in the ordering section above. Buying the system is usually the better value where you need both arms plus the track.
Is the Ergotron LX Sit-Stand Wall Mount System covered by warranty in Singapore?
Yes. Every Ergotron LX Sit-Stand Wall Mount System sold by SourceIT comes with local Singapore warranty and a GST invoice; Ergotron backs the LX Sit-Stand Wall Mount System with a 10-year manufacturer warranty.
