Humanscale M4Y Monitor Arm Wall Mount
Six Bracket Styles (N1, N2, T1, B1, B2, B3) are available to support one or multiple monitors in any display environment.
Bracket Styles are divided into three primary categories based on application: No-Post Brackets(N1, N2), Top-Mount Bracket (T1) and Bracket Mounts (B1, B2, B3).
A. No-Post Brackets- Are designed for vertical surfaces such as slat wall, panels or wall studs. They are available for one or two monitors.
N1 - No-Post Bracket for One Monitor
N2 - No-Post Bracket for Two Monitors
B. Top Mount Brackets- Insert directly into a Post to support the Monitor Arm at a fixed position at the top of the Post. Top-Mount Brackets provide a continuous, clean look extending from the Post, and are an excellent choice when used with an M4 Adjustable Arm or M7 with FEA because the Bracket itself cannot be adjusted along the Post.
T1 - Top Mount Bracket
N1 : No-Post Bracket for One Monitor
N2 : No-Post Bracket for Two Monitors
T1 : Top Mount Bracket
C. Bracket Mounts- In contrast to Top-Mount Brackets, fit over the Post and are designed to support the Monitor Arm anywhere along the Post (above the Friction Knob on Standard and Horizontal Stackable Posts). In this way, the dedicated user (in non-shared environments) can set the monitor at the optimal height without the need to readjust it vertically.
B1 - Bracket Mount for One Monitor
B2 - Bracket Mount for Two Monitors
B3 - Bracket Mount for Three Monitors
B1 : Bracket Mount for One Monitor
B2 : Bracket Mount for Two Monitors
B3 : Bracket Mount for Three Monitors

M4 Adjustable Monitor Arm Styles:
M4 Adjustable Monitor Arm styles offer 11.5” of dynamic, one-touch vertical adjustment and are ideal for workstations supporting multiple users or where dynamic adjustment is required.
Both Adjustable and Non-Adjustable Arms are available with all Bracket Styles (No Post Brackets, Top-Mount Brackets, andBracket Mounts).
For M4 two arm styles are available:
B : Adjustable Single Link Arm
A : Adjustable Double Link Arm
Humanscale offers a variety of monitor arm mounting options to accommodate any workstation environment. Mounting styles are dependent on the surface to which the monitor arm is being mounted, the monitor application, the desired degree of adjustability, and the weight of the monitor. Mounts are divided into two primary categories:
Horizontal Surface Mounts: are used to mount posts to horizontal surfaces such as desks, counters, tabletops and other work surfaces.
NM - No Mount
BT - Bolt Through Mount
CM - Heavy Duty Clamp Mount
LC - Low Profile Two Piece Clamp Mount
LP - Low Profile One Piece Clamp Mount
DM - Direct Mount
BT: Bolt Through Mount
CM: Heavy Duty Clamp Mount
LC: Low Profile Two Piece Clamp Mount
DM: Direct Mount
LP: Low Profile One Piece Clamp Mount
Vertical Surface Mounts: enable monitor arms to be affixed vertically to walls such as slatwall, panels or wall studs, and may or may not support a post, depending on style. There are three styles of Vertical Surface Mounts: Slatwall Mounts, Panel Mounts and Wall Stud Mounts.
Slatwall Mounts- There are two styles of Slatwall Mounts: Standard Slatwall Mounts (support single or multiple monitors and/or posts to mount monitors higher than mounting point) and Universal Slatwall Mounts (compatible with numerous slatwall systems to support one monitor only; not compatible with posts).

Humanscale offers three Post styles to accommodate a range of requirements. There are three different Post Styles: Standard Posts, Slim Posts and Stackable Posts.
Standard Posts: Standard Posts are comprised of a large outer tube and narrow inner pole and are appropriate for heavy-duty applications such as workstations requiring multiple monitors. They may be adjustable or non-adjustable in height, and are available only in one-row configurations.
NP: No Post
SP: Standard Post, Non-Adjustable
Slim Posts: Slim Posts are appropriate for lightweight applications such as workstations requiring only one or two smaller monitors. The diameter of the Slim Post is the same for the entire length of the post making it easy to adjust B1 or B2 brackets anywhere along the post height.
SL Slim Post
SP: Standard Post, Top Mounted
SP: Standard Post, Bracket Mounted
SL: Slim Post, Top Mounted
SL: Slim Post, Bracket
Stackable Posts: Stackable Posts support up to two rows of one to three monitors per row. Stackable Posts can also be used to raise the position of a single arm (for example, one monitor positioned 30” above the surface). Stackable Posts are available for both horizontal and vertical surfaces. Stackable Posts are the only solution available for Vertical Mounting Surfaces.
Stackable Posts for Horizontal Surfaces- Stackable Posts for Horizontal Surfaces are used with monitor arms that are mounted to horizontal surfaces such as desks, counters, and tabletops.
1H: One-Row Stackable Post for Horizontal Surfaces
2H: Two-Row Stackable Post for Horizontal Surfaces
TH: Top Row Stackable Post
Stackable Posts for Vertical Surfaces- Stackable Posts for Vertical Surfaces are used with monitor arms that are mounted to vertical surfaces such as slatwall, panel systems, or wall studs.
