The Humanscale M4 arm is available in two different finishes. Black and Silver are both standard colors.
Post Height* (distance from top of desk mount to top of post)
Bolt Through (BT)
Secures your M7 post to your work surface via a bolt.
Heavy Duty Clamp Mount (CM)
An extra secure clamp for heavy, multiple-monitor applications. Not necessary for a single monitor, even larger monitors.
Low profile two-piece clamp mount (LC)
Similar to the low-profile one piece but comes apart for "against the wall" applications where you can't slide a one piece mount into place.
Low profile one-piece clamp mount (LP)
Humanscale's clamp mounts are very secure. This is the most common clamp choice and is as suitable for multiple monitors as the other clamp mounts.
Direct Mount (DM)
Screws to the top of your work surface.
