Humanscale M4 Monitor Arm - Design Your Own Solution

item#: HUS060

The Humanscale M4 monitor arm is the most versatile and heavy duty monitor arm on the market and features a reliable, modular design that easily accommodates up to 6 monitors and provides for easy upgrading as your needs change. Unlike the Humanscale M7, the Humanscale M4 links offer both vertical and horizontal adjustability, negating the need for additional height adjustment controls.

Humanscale has discontinued this item.
The Humanscale M8 Monitor Arm is a great replacement.

Select the finish you'd like for your Humanscale M4 Monitor arm

The Humanscale M4 arm is available in two different finishes. Black and Silver are both standard colors. Polished aluminum is available but extends lead time to 12-16 weeks.

M4 Finish Options

Determine the correct bracket

Humanscale M4 Monitor arms are suitable for both single and multiple monitor configurations.

If you plan on only mounting 1 monitor, you have three bracket styles to choose from. T1 is the most popular. B1 allows for some height adjustment. N1 would be for panel or wall mounts where you do not intend to use a post.

For two monitor configurations, you can either opt for the bracket mounted B2, the no-post N2 or if you want them vertically stacked, you would need 2 B2 brackets with either a 1H or 2H stackable post (see below for post options).

Select the links for your monitor arm

Humanscale M4 is available with either 1 closed link or with two links, one closed and one open. Drawings illustrate total depth of each arm link option. It is possible to order different link configurations on each arm for a multiple monitor or accessory application.

Select how your arm will mount to your desk, wall, slat wall or panel

Humanscale offers 6 different desk mounting options, plus 2 wall mount and panel mounts for most accessory rail, slatwall and wall system panels. Note that if you plan on a panel mount and a mutiple monitor solution, the brand of panel you have is critical as the universal panel mount will only support one monitor. The term "Row" refers to rows of monitors. If you wanted one or more monitors on top of each other, you would mount them in rows.

Horizontal Mount Applications
M7 Bolt-through Mount

Bolt through (BT)

Secures your M7 post to your work surface via a bolt.

M7 clamp mount

Heavy duty clamp mount (CM)

An extra secure clamp for heavy, multiple-moniotr applications.

M7 low profile 2 piece clamp mount

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.

M7 low-profile clamp mount

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.

M7 direct mount

Direct mount (DM)

Screws to the top of your work surface.

M7 grommet mount

Grommet Mount (GM)

Many desks come equipped with a pre-drilled 2.5" diameter grommet hole making installation of your monitor arm fast and secure. Note that use of a grommet mount allows for additional height adjustments as the post can be slid down into the hole to lower your pole height.

Wall and Panel Mounts Applications
M7 standard wall stud mount

Standard wall stud mount (WD)

This mount is suitable for multiple monitors.

M7 wall stud mount

Knuckle wall stud mount (WK)

The knuckle wall mount offers an extra point of pivot for added adjustability.

Universal Wall Stud Mounts

2-piece universal wall stud mount (WU)

A great option for those who don't like visible screw holes. Suitable for single monitor use only.

Choose Your Post and Height Adjustment Features

Humanscale M4 link arms offer significant height adjustability that is adequate for most applications. Humanscale does offer adjustable height posts and front end adjusters. Please contact us if you need these.

Standard Posts -

Standard posts feature a large outer tube and a narrower inner pole that does not slide into the larger tube for height adjustment. These posts are heavy duty and great for heavier monitors or multiple monitor configurations but are only available for one row configurations. In other words, they are not suitable for applications where you want one or more monitors above another. Standard posts are only suitable for horizontal mounting.

Standard post options include:

  • NP: No post - only for wall or panel mount
  • SP: Non-adjustable

Slim post -

The slim post is also designed for mounting on horizontal surfaces and the slim post is not height adjustable but when used with a bracket mount, the bracket can move up or down the entire length of the slim post providing for easy height adjustment. Slim posts are better for light duty and one or two monitor configurations with a maximum monitor weight of 30 lbs.

Note that maximum height is slightly less for bracket mount. The slim post cannot be used with a grommet mount.

Stackable Posts -

Stackable posts are designed for multiple monitor configurations where you wish to stack monitors in rows. Stackable posts can support up to two rows of up to 3 monitors each. Stackable posts can also be used with a single monitor if you wish a greater height for your monitor. Stackable posts can be used with any mount on a horizontal surface, or with wall and panel mounts.

Options for Horizontal mounts -

  • 1H: One row stackable post
  • 2H: Two row stackable post for mounting one or more monitors above one or more monitors
  • TS: Top row stackable post - can be added to an existing 1H or 1V to create a second row.

Options for Vertical (wall and panel) mounts -

  • 1V: One row stackable post
  • 2V: Two row stackable post

M7 2HM7 2V

Humanscale M4 Options:

Crossbars -

Crossbars offer the ability to mount two or three monitors so that they move up and down in unison. Each monitor mount features a ball pivot joint for independent viewing angle adjustment. Each crossbar requires 2 link arms for mounting and must be used with a bracket mount for height adjustability. Either standard or folding links can be used but folding links will fold flatter.
