Chief KMA220B Dual Horizontal Monitor Accessory

The KMA220B turns a single Chief K-series swing arm - wall or desk - into a two-screen position, holding both flat panels side by side off the one arm. Each screen keeps its own adjustment rather than being locked to its neighbour, so you can toe them in toward the chair independently, and Centris TurnTite dials hold each setting once it is right instead of letting it creep back over a week of use.

It takes any panel with a VESA 75 x 75 mm or 100 x 100 mm hole pattern. Two numbers matter when you size the arm: the 11 lb (5 kg) capacity is per monitor, not for the pair, and fitting the accessory reduces the host mount's own weight capacity by 7 lbs. Order it by Chief part number KMA220B.
