Thinking Works Vader Monitor Arm – Single or Dual, Black or White

Thinking Works Vader monitor arm, single or dual, black or white

Thinking Works' gas-spring monitor arm, built to be adjusted from a seated position: the gas spring counterbalances a 17 to 32-inch screen of 1 to 9 kg so it lifts, lowers and swings with one hand and holds position, and a built-in tension gauge shows where to set the spring for your screen. Thinking Works' shorter front arm keeps the screen close to the post and lets two screens sit edge to edge on the dual.

Single (VA-MA-1100) or dual (VA-MA-1200), in matte white with white trim or satin black with black trim, with an optional laptop tray (VA-MA-1500). Desk clamp and bolt-through mount both in the box; pre-assembled in the carton.
