Ergotron LX Dual Desk Mount Side-by-Side Arm Polished Aluminum
PRODUCT DESCRIPTION
Ergotron LX Dual Desk Mount Side-by-Side Arm Polished Aluminum (45-245-026) - 10 Years Local Warranty
Two Monitors at Eye Level, Side by Side
The LX Dual Side-by-Side Arm places two displays at matched height on one pole, giving a continuous panoramic working surface across both screens. Each arm articulates independently with 360° pan and 360° rotation, so you can angle the pair inward into a shallow arc, run one screen in portrait for documents and code, or split them apart for collaborative review.
Constant Force™ Adjustment for Two Displays
Ergotron's Constant Force™ technology means each screen moves with a fingertip and holds its position without sagging - important when two monitors share a single pole and small misalignments are immediately visible. Each arm delivers 33 cm (13 in) of lift, 75° of tilt and up to 64 cm (25 in) of extension.
Frees the Desk Beneath Both Screens
Removing two factory stands recovers a substantial area of worksurface - typically enough for a docked laptop, a document tray and a full-size keyboard. For Singapore offices working with 1200 mm and 1400 mm desks, that reclaimed depth is often the difference between a cramped desk and a comfortable one.
Rated for 18.1 kg Across Both Arms
Each arm supports 3.2 kg to 9.1 kg (7-20 lbs), with a combined ceiling of 18.1 kg (40 lbs). Ergotron specifies a typical display size of 27 inches per screen, and mounting uses the standard VESA 100 x 100 mm or 75 x 75 mm pattern. Cables route beneath the arms for a clean, professional dual-display workstation.

Compatibility & Fit
The LX Dual Side-by-Side Arm carries two displays at the same height on a single pole. Each display may weigh 3.2 kg to 9.1 kg (7-20 lbs), with a combined maximum of 18.1 kg (40 lbs) across both arms. Ergotron specifies a typical display size of 27 inches per screen. Both arms use the VESA FDMI MIS-D pattern in 100 x 100 mm or 75 x 75 mm.
Mounting is by the included standard two-piece desk clamp on all three finishes. The polished aluminium 45-245-026 additionally ships with a white grommet mount kit for mounting through an existing cable hole; the matte black and white versions ship with the clamp only. Allow enough clear desk width behind the mounting point for both arms to swing without striking a partition.
Two 27-inch panels side by side is the configuration this arm is built around. Ultrawide or curved screens are workable on a single arm provided each stays within the 9.1 kg per-display limit, but a pair of ultrawides will usually run out of horizontal desk space before it runs out of arm capacity - consider the stacking version instead if the desk is narrow.

Frequently Asked Questions — Ergotron LX Dual Side-by-Side Arm
How many monitors does it hold and at what size?
Two, mounted side by side at equal height. Ergotron specifies a typical display size of 27 inches per screen, with each display weighing 3.2 kg to 9.1 kg (7-20 lbs) and a combined maximum of 18.1 kg (40 lbs).
Which finishes are available and what differs between them?
Polished aluminium (45-245-026), matte black (45-245-224) and white (45-491-216). Mechanically they are identical. The difference is what ships in the box: only the polished aluminium version includes the white grommet mount kit.
Should I choose side-by-side or stacking?
Side by side suits wide desks and work that spans two screens horizontally - trading, monitoring, comparing documents. If your desk is narrow, or you want a reference screen above your main display, the LX Dual Stacking Arm puts one monitor above the other on the same desk footprint.
What mounting options does it support and will it fit my desk?
All three finishes include the standard two-piece desk clamp, which needs no drilling. The polished aluminium model also includes a grommet mount for fitting through an existing cable hole. Check that there is clear space behind the mounting point for both arms to move.
Do my monitors need to be VESA compatible?
Yes - VESA FDMI MIS-D, 100 x 100 mm or 75 x 75 mm. Both displays need a compatible pattern, though they do not have to be the same make or model. Non-VESA monitors require an adapter plate from the display manufacturer.
Can I run one screen in portrait?
Yes. Each arm rotates a full 360°, so you can run either or both displays in portrait - a common setup for developers, legal document review and long-form editing - and tilt each one independently through 75°.
Does the Ergotron LX Dual Side-by-Side Arm come with a Singapore warranty?
Yes. Every Ergotron LX Dual Side-by-Side Arm sold by SourceIT comes with local Singapore warranty and a GST invoice; Ergotron backs the LX Dual Side-by-Side Arm with a 10-year manufacturer warranty.
