Ergotron HX Triple Monitor Bow Kit Polished Aluminum
PRODUCT DESCRIPTION
Ergotron HX Triple Monitor Bow Kit Polished Aluminum (98-009-026) - 10 Years Local Warranty
Take an HX Monitor Arm From One or Two Screens to Three
The Ergotron HX Triple Monitor Bow Kit (98-009-026) converts an existing HX Single or HX Dual monitor arm into a three-screen workstation. A triple hinged bow, three monitor pivots and a positioning handle bolt onto the arm you already own — no second desk fixing, no second wall bracket, no extra desk footprint. It is the standard route for Singapore trading desks, NOC and security positions, dealing rooms and engineering benches that outgrow two screens.
Three Displays up to 26 Inches, 30.6 lbs Total
Each pivot carries 2.0–10.2 lbs (1.0–4.6 kg) for a combined 6.0–30.6 lbs (3.0–13.8 kg) across the three screens, at up to 26″ per display. That is the practical envelope for a triple-monitor trading or monitoring wall built on a single arm, and it is deliberately lighter than the host arm's own rating because the load is now split three ways.
A Hinged Bow That Wraps the Screens Around the User
The bow pivots 40° inward and 90° outward, so the three panels can be curved into a tight arc that keeps every screen square to the eye, or opened flat to share with a colleague. Each monitor pivot adds 70° of backward tilt, 5° forward, 360° of pan and portrait/landscape rotation with lockout, so an individual screen can be set to portrait for logs, code or long documents.
Constant Force Lift Carries All Three Together
Because the kit hangs off an HX arm, it inherits the arm's Constant Force™ lift — 11.5″ (29.2 cm) of one-touch height adjustment and up to 24.5″ (62.2 cm) of reach for the whole three-screen assembly. The included handle makes repositioning the bank straightforward during fit-out and shift changes.
Polished Aluminium Finish for Open-Plan Singapore Offices
The 98-009-026 is the polished aluminium finish, matched to the polished aluminium HX arms SourceIT stocks for desk and wall installation. Overall the configured bank measures 26″ (660 mm) wide and sits between 33″ and 44″ (838–1117 mm) high, with a working depth of 9.7″ to 24.5″ (246–622 mm) from the mounting point.

Compatibility & Fit
The bow kit is a conversion kit, not a mount. It requires an HX Single or HX Dual Monitor Arm — desk or wall — which is ordered separately. Its own weight and size limits are much lighter than the host arm's, because the load is now split three ways.
| VESA Pattern | MIS-D 100/75 C — 100 x 100 mm and 75 x 75 mm |
| Screen Size | Up to 26″ per display |
| Weight Per Screen | 2.0–10.2 lbs (1.0–4.6 kg), measured without the factory stand |
| Total Load | 6.0–30.6 lbs (3.0–13.8 kg) |
| Number of Screens | Three |
| Host Arms | HX Desk Monitor Arm (45-475), HX Wall Monitor Arm (45-478), HX Dual Monitor Desk Arm (45-476), HX Wall Dual Monitor Arm (45-479) |
| Mounting Type | Attaches to the host HX arm — no additional desk or wall fixing required |
| Desk Thickness | Unchanged — governed by the host HX arm already installed |
Check your screens against the 26″ and 10.2 lbs limits, not the arm's. An HX Desk arm on its own carries a single large panel at up to 42 lbs; with the bow kit fitted, each of the three screens must be 26″ or smaller and 10.2 lbs or lighter. Typical 24″ office and trading monitors fit comfortably; 27″ and 32″ panels generally do not.
Panel depth matters. Ergotron recommends monitors no thicker than 1.5″ (38 mm); beyond that the 2.5″ (63 mm) crossbar hinge travel is reduced and the bank cannot be curved as tightly.
Ultrawide and curved screens: not applicable here — a triple bank is built from three conventional panels. For a single large curved ultrawide, use the HX Desk Monitor Arm with HD Pivot or the HX Heavy-Duty Tilt Pivot instead.

Frequently Asked Questions — Ergotron HX Triple Monitor Bow Kit
What finishes does the HX Triple Monitor Bow Kit come in?
Polished aluminium (98-009-026, this listing) and white (98-009-216). The mechanics are identical — choose the finish that matches your HX arm.
What monitor size and weight does the bow kit support?
Three displays up to 26″ each, weighing 2.0–10.2 lbs (1.0–4.6 kg) per screen and 6.0–30.6 lbs (3.0–13.8 kg) in total, measured without the factory stands. These limits are the kit's own and are lighter than the host arm's.
Does this include the monitor arm?
No. The kit supplies the triple bow, three pivots, the handle and hardware only. You need an HX Single or HX Dual Monitor Arm as well — SourceIT stocks the HX Desk Monitor Arm and the HX Wall Monitor Arm among others.
Which HX arms is it compatible with?
The HX Desk Monitor Arm (45-475), HX Wall Monitor Arm (45-478), HX Dual Monitor Desk Arm (45-476) and HX Wall Dual Monitor Arm (45-479). Both desk-mounted and wall-mounted hosts work.
Do I need extra desk space or a second fixing?
No. The bow attaches to the arm you already have, so there is no additional desk clamp, grommet or wall bracket — and no extra desk footprint. The host arm's existing desk-thickness limits continue to apply unchanged.
Do I need a VESA adapter?
Not for standard displays — each pivot provides VESA MIS-D 100 x 100 mm and 75 x 75 mm. Screens with a larger or proprietary pattern need the manufacturer's own adapter plate.
Can I run one of the three screens in portrait?
Yes. Each pivot rotates between portrait and landscape with an optional lockout, so any of the three can be set to portrait — a common arrangement for log monitoring, code review and long documents alongside two landscape screens.
How does this compare with buying a second dual arm?
A second HX Dual Monitor Desk Arm gives you four heavier screens but needs a second desk clamp or grommet and more desk edge. The bow kit adds a third screen to the arm already installed, at a lower per-screen weight limit — the right choice when desk edge, not screen weight, is the constraint.
Does the HX Triple Monitor Bow Kit come with a Singapore warranty?
Yes. Every Ergotron HX Triple Monitor Bow Kit sold by SourceIT comes with local Singapore warranty and a GST invoice; Ergotron backs the HX Triple Monitor Bow Kit with a 10-year manufacturer warranty.
