Monitor Arm Wall Mount Bracket for 13-34 inch Monitor & Small TV, Height Adjust

The ergonomic arm features -35°/+35° tilt, ±90° swivel, and 360° rotation, allowing perfect screen positioning to reduce neck, shoulder, and back strain for optimal comfort. Simply use the included Allen key to fine-tune the tension—turn the knob clockwise ("+") if the mount won't lift, or counterclockwise ("-") if it won't lower.
