3M MMMAKT180LE Adjustable Keyboard Tray Sit-stand Arm

Product Description

The 3M MMMAKT180LE is an adjustable keyboard tray with a sit-stand arm designed for ergonomic workstation setups. The arm raises the keyboard platform up to 10 inches above the mounting surface and tilts up to 15 degrees forward or backward, allowing the operator to work comfortably in both seated and standing positions. A lever-free adjustment mechanism makes repositioning quick and tool-free. The platform slides left or right for precise positioning, and the attached mouse platform mounts on either side with multi-directional adjustment. Gel wrist rests with antimicrobial leatherette covers are included. Installed by office furniture technicians or facilities staff, this tray suits professional ergonomic workstation builds.

The MMMAKT180LE is built for corner workstations with a track length of 23 inches. It is specifically designed for corners with less than a 12-inch radius or a 17-inch diagonal measurement. This makes it well suited for L-shaped and corner desk configurations common in office and administrative environments. The tray is not compatible with shallow workstations. The mouse platform adjusts up, down, forward, and back to accommodate a range of user preferences and desk configurations.
