counterbalance monitor arm

Most models support the common 75×75 mm and 100×100 mm VESA bolt-hole patterns.

Ranges vary by model but typically include: tilt (often up to ±90°), swivel across multiple joints (commonly up to ~180°), full 360° rotation for portrait/landscape, and several inches of vertical travel — some dual-arm models list about 13 inches of raise/lower.

Most arms use an adjustable spring or gas-spring mechanism with a tension screw or hex bolt. Turning that fastener increases or decreases the spring tension so the arm will hold the screen in place or move more easily.

Common mounting options include desk-edge C-clamps and grommet-through installations; some models also offer wall or pole mounting. Many listings include hardware for clamp or grommet setups.

They use spring-assisted mechanisms — typically gas springs or mechanical springs — that counterbalance the display’s weight, allowing smooth hand adjustments for raising, lowering, tilting, swiveling, rotating and extending the screen.

Most are made from metal for strength — commonly steel for structural parts and aluminum or aluminum alloy for lighter components.
