WHY THE PRICE IS JUSTIFIED

Its premium is explained by an aluminum commercial-grade structure, Constant Force mechanical counterbalance, 25-inch reach, unusually easy installation, 10,000-cycle durability testing and a 10-year warranty. The $199 street price is compelling; near MSRP, value is weaker but still defensible for daily repositioning and long ownership.

MATERIALS

Arm, extension and baseDie-cast aluminum

High stiffness-to-weight and tighter, more durable joints than thin stamped arms.

Counterbalance mechanism and hardwareSteel

Constant Force spring maintains repeatable lift without a gas seal that can leak.

CRITERIA

Counterbalance Match

Structural Rigidity

Reach & Fit

Up to 25 in extension, 13 in lift, VESA 75/100, 4–22 lb and screens to 34 in.
