BenQ BSL01 Single Monitor Arm 17"-40" 11kg Ergo Arm
PRODUCT DESCRIPTION
BenQ BSL01 Single Monitor Arm 17"-40" 11kg Ergo Arm (BSL01) - Local Warranty
Where the BSL01 Sits in BenQ's Five-Arm Ergo Range
The BSL01 is the single-screen arm in BenQ's lighter Ergo tier and the most affordable of the five. It uses a mechanical spring tested to 20,000 cycles rather than the gas spring of the BSH01 and BSH02, carries 2-11 kg instead of 2-20 kg, takes screens to 40" rather than 45", and ships without a reinforcement plate. What it gains is reach of movement: 68° to -45° of tilt against 50° to -20° on the heavy-duty arms, plus a visual tension indicator. At 2.84 kg it is also the lightest arm in the range to handle and install.
Visual Tension Indicator for Guess-Free Setup
Balancing a spring arm normally means turning an adjustment screw and watching whether the screen drifts — slow, imprecise, and frequently abandoned half-finished. The BSL01 has a built-in tension indicator that shows whether the arm is correctly set for the panel fitted, so it can be balanced right the first time and then moves smoothly every day afterwards. On a floor-wide deployment across a Singapore office that removes a per-desk support call, and it means a hot-desk arm can be re-balanced quickly when a different screen is fitted.
68° of Tilt for Sit-Stand Desks and Shared Screens
The BSL01 tilts 68° up and -45° down, a far wider arc than the heavy-duty arms offer. That earns its keep on a sit-stand desk, where the panel has to angle down sharply when the user stands, and in shared spaces where a colleague steps round to read the screen. Extension reaches 550 mm, swivel is 90° either side, and the head pivots a full 180° in each direction, so the panel can be turned into portrait for code review, long documents or a monitoring wall.
Clamp or Grommet, Top-Mounted, with Cable Management Built In
Fitting is by C-clamp on the rear desk edge or through a grommet hole, and both tighten from above, so no one has to work under a loaded workstation. The clamp accepts desk tops 10 to 50 mm thick, a wider window than the heavy-duty arms manage without their plate. Cable channels run along the arm so HDMI, DisplayPort, USB-C and power cables follow the arm instead of crossing the desktop — which matters in open-plan areas, meeting rooms and any space where screens are moved regularly.

Compatibility & Installation
Desk mounting
C-clamp onto the rear edge of the desk, or grommet mount through an existing cable hole. Both are top-mounted. Desk thickness of 10 to 50 mm is supported. No reinforcement plate is supplied with this model; for glass or unusually thin tops, specify the BSH01, which includes one.
What it holds
Any monitor from 17" to 40" with a VESA 75 x 75 mm or 100 x 100 mm pattern, weighing between 2 kg and 11 kg. Webcams, light bars and soundbars bolted to the panel count towards that limit.
Movement
Extension up to 550 mm, tilt 68° to -45°, swivel 90° either side, and 180° pivot in each direction for portrait use. The built-in tension indicator confirms the arm is balanced for the panel fitted.
Cable management
Integrated cable channels run along the arm so video and power cables follow the arm rather than crossing the desktop.

Frequently Asked Questions — BenQ BSL01
How does the BSL01 differ from the BSH01?
The BSL01 uses a mechanical spring tested to 20,000 cycles, carries 2-11 kg, fits screens to 40" and has no reinforcement plate. The BSH01 uses a gas spring tested to 25,000 cycles, carries 2-20 kg, fits screens to 45" and includes a steel plate. The BSL01 tilts further, 68° to -45° against 50° to -20°, and has a visual tension indicator.
Which arm do I need for a 32" monitor?
The BSL01 is rated to 40", so a 32" panel is within its size range — but check the weight. If the panel exceeds 11 kg, specify the BSH01 instead.
What is the tension indicator for?
It shows whether the arm's spring tension matches the weight of the screen fitted, so the arm can be balanced without trial and error and moves smoothly afterwards.
Can I fit it to a glass desk?
BenQ does not supply a reinforcement plate with the BSL01. For thin or glass tops, specify the BSH01. The BSL01 clamp itself fits tops 10 to 50 mm thick.
Does it rotate to portrait?
Yes, 180° to -180° screen rotation, in either direction.
Does the arm have USB ports?
No. BenQ does not list an integrated USB hub on the BSL01. Cables are routed through the arm only.
Do I need access under the desk?
No. Both the clamp and the grommet fitting are top-mounted.
What warranty and invoice do I get?
Every unit sold by SourceIT carries a local Singapore warranty and is supplied with a GST invoice.
