Ergotron LX Dual Stacking Arm Matte Black
PRODUCT DESCRIPTION
Ergotron LX Dual Stacking Arm for Displays up to 24" Matte Black (45-492-224) - 10 Years Local Warranty
Two Screens on a Single Desk Footprint
The LX Dual Stacking Arm places one monitor directly above the other, so a two-screen setup takes no more desk width than a single display. That makes it the practical answer for narrow desks, benching systems and hot-desk layouts where a side-by-side pair simply will not fit - a common constraint in Singapore office fit-outs.
Constant Force™ Motion on Both Arms
Each arm uses Ergotron's Constant Force™ technology, giving 33 cm (13 in) of lift, 75° of tilt, 360° of pan and 360° of rotation with fingertip effort and no drift. Extension reaches 64 cm (25 in), so the upper screen can be pulled forward for reading and pushed back out of the way when you need the desk.
Monitor-Over-Laptop Configuration
The polished aluminium 45-248-026 ships with a notebook tray rated for 1.1 kg to 5.4 kg (2.5-12 lbs) in place of a second monitor mount, letting you raise a laptop to a comfortable height beneath your main display. It is a clean solution for staff who dock a notebook at a shared desk each morning.
Rated for Displays up to 24 Inches
Each arm supports a display of up to 24 inches weighing 3.2 kg to 9.1 kg (7-20 lbs), with an 18.1 kg (40 lbs) combined ceiling. Mounting uses the standard VESA 100 x 100 mm or 75 x 75 mm pattern, and cables route beneath the arms to keep the stacked pair looking tidy.

Compatibility & Fit
The LX Dual Stacking Arm mounts two displays of up to 24 inches, one above the other, on a 33 cm 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). Both arms use the VESA FDMI MIS-D pattern in 100 x 100 mm or 75 x 75 mm.
All three finishes include the standard two-piece desk clamp. The polished aluminium 45-248-026 also ships with a grommet mount and a notebook tray, letting you run a monitor above a laptop instead of two screens. The notebook tray carries 1.1 kg to 5.4 kg (2.5-12 lbs). The white and matte black models ship with the clamp only.
Because the displays sit vertically, the deciding factor is height rather than desk width - allow clearance above the desk for the upper screen at your preferred eye level. If you need larger panels than 24 inches, or three to four screens, step up to the tall pole version, which takes displays up to 40 inches on a 23-inch (58 cm) pole and expands with accessory arm kits.

Frequently Asked Questions — Ergotron LX Dual Stacking Arm
How many monitors does it hold and how large can they be?
Two displays of up to 24 inches each, stacked vertically. Each screen 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.
Which finishes are available and what is different between them?
Polished aluminium (45-248-026), matte black (45-492-224) and white (45-492-216). The mechanics are identical. The polished aluminium version is the fullest package - it includes the grommet mount and a notebook tray, neither of which ships with the white or matte black versions.
Can I mount a laptop instead of a second monitor?
Yes, if you have the notebook tray. It is supplied with 45-248-026 and available separately as the Ergotron Notebook Tray (50-193-200). It carries 1.1 kg to 5.4 kg (2.5-12 lbs).
What mounting options are supported and will they fit my desk?
Every finish includes the standard two-piece desk clamp, which requires no drilling. The polished aluminium model adds a grommet mount for fitting through an existing cable hole. Allow vertical clearance above the desk so the upper display can reach your eye level.
Do I need VESA-compatible monitors?
Yes - VESA FDMI MIS-D, 100 x 100 mm or 75 x 75 mm. Displays without VESA holes need an adapter plate from the monitor manufacturer.
What if my monitors are larger than 24 inches?
Move up to the tall pole version, the LX Dual Stacking Arm, Tall Pole, which takes displays up to 40 inches on a 23-inch (58 cm) pole and can be expanded to three or four screens with the LX Arm, Extension and Collar Kit.
Does the Ergotron LX Dual Stacking Arm come with a Singapore warranty?
Yes. Every Ergotron LX Dual Stacking Arm sold by SourceIT comes with local Singapore warranty and a GST invoice; Ergotron backs the LX Dual Stacking Arm with a 10-year manufacturer warranty.
