metal adjustable arm clamp

Most clamp-on monitor arms support the two standard VESA patterns: 75×75 mm and 100×100 mm.

Ranges vary by model, but common capabilities are: tilt roughly −50° to +50°, swivel about ±90° to 180°, full 360° rotation (for portrait/landscape), arm extension around 15–24.8 inches, and height adjustment on the order of roughly 17.5–19.6 inches. Exact ranges depend on the specific arm.

Clamp monitor arms are typically made from aluminum alloys and powder-coated or heavy-duty steel. Listings often emphasize high-strength or aerospace-grade aluminum and robust steel construction for stability and long-term durability.

Many clamp-on arms include built-in cable management such as plastic or integrated cable clips along the arm, hollow arm channels or a center pole for routing wires, and removable or detachable VESA plates that let you route cables neatly when mounting or servicing the monitor.

Most clamp-on arms are designed for common monitor sizes in the roughly 13–32 inch range. Heavy-duty or ultrawide models in the listings extend support into larger sizes (examples cite 27–57 inches), and one listing notes compatibility up to 65 inches—these are exceptions rather than the norm.

Most products offer both C-clamp and grommet mounting options. Desk-thickness ranges vary by model; examples in the data cite fits from about 0.39 inches up to roughly 3.3–3.5 inches. Verify the model’s specified clamp or grommet range before installation.
