    Find the ideal keyboard solution for your work style with the Humanscale 700 Diagonal Corner Keyboard Tray, which was designed to fit on angled or corner desks to bring your board closer to your Neutral Reach Zone.

    This keyboard tray features a sturdy platform with angled edges in the rear, and is designed to fit the angled edges of a diagonal corner. This is great news for users of desks with less straightforward configurations, as it allows you to mount a keyboard tray in trickier corners.

    The tray is constructed of phenolic to create an ultra-strong, remarkably thin 1.25 inch composite that's non-toxic, durable, and easy to clean.

    The Humanscale 700 Diagonal Corner Keyboard Tray is ready to deliver comfort-transforming work to offices everywhere, and is now available with a Design Your Own option.


    • Easily configured to meet your specific needs 
    • 700 board offers diagonal-cut corners on the back corners to better fit corner desks or workstations with small keyboard tray cutouts
    • Made of phenolic - an ultra-strong, remarkably thin (1/4") composite that's nontoxic, durable, and easy to clean
    • Platform design works with all the mousing platforms options available and will fit most desks, including corner desks

    Track lengths 11" - 27" for varying desk depths

    Humanscale Keyboard Mechanisms

    2G mechanism

    Loosen knob to adjust and lock back into place. Unlike the 5G or 6G, this mechanism has no reference for keyboard platform angle.

    Height adjustment 6.25": 1.25" above track to 5" below track
    Track length Comes standard with 22" track

    6G mechanism

    Humanscale's newest dial-a-tilt mechanism that instantly adjusts the platform's tilt without the need to lock or loosen any knobs or levers and slimmer than the 5G.

    Height adjustment 7": 1.75" above track to 5.25" below track
    Track length Comes standard with 22" track

    5G mechanism

    The dial-a-tilt mechanism instantly adjusts the platform's tilt without the need to lock or loosen any knobs or levers. Its solid build quality and simplicity make this mechanism the most popular mechanism Humanscale offers.

    Height adjustment 6.25": 1.25" above track to 5" below track
    Track length Comes standard with 22" track

    5GSM mechanism for limited-depth desks

    This mechanism goes 4" farther underneath a desk surface, getting a keyboard tray stored out of the way on a shorter track, perfect for desks with limited depth or small spaces.

    Height adjustment 4": 0.5" above track to 3.5" below track
    Track length Comes standard with 18" track

    5GAD mechanism for above-desk use

    This mechanism's greater-than-average adjustment range is ideal for sit-to-stand workstations, featuring steel construction for stable keying and mousing.

    Height adjustment 13.5": 7.5" above track to 6" below track
    Track length Comes standard with 27" track

    4G mechanism

    Height adjustment 6.25": 1.25" above track to 5" below track
    Track length Comes standard with 22" track

    4GAD mechanism for above-desk use

    This is a version of the 4G with a longer arm for use above a work surface, making it great for sit-to-stand solutions.

    Height adjustment 11.5": 8.5" above track to 3" below track
    Track length Comes standard with 27" track

    KM mechanism

    This mechanism features a pre-set 0 degree tilt and knob-free adjustment.

    Height adjustment 6.25": 1.25" above track to 5" below track
    Track length Comes standard with 22" track

    Lateral Slider

    All Humanscale mechanisms pivot 360 degrees from the point where it is mounted to the track. Some users have a need for additional side-to-side adjustability. The lateral slider provides for eight extra inches of movement from right to left. This is a useful feature for someone at a large workstation that requires them to type facing different angles or monitors.


    Mouse Platform

    Clip Mouse - Mousing Platform

    The clip mouse platform is the only mouse platform that allows the user total adjustment control in all three dimensions- height, depth, forward/back and tilt, allowing it to be adjusted precisely the way you need it. It also easily snaps onto either side of the tray for left or right use, and it's available in two sizes and different height ranges.

    Note: The high clip has an extra one inch height for additional adjustment and usability and is the most popular accessory we sell.

    90 8.5'' diameter
    91H 10'' diameter high

    Humanscale Clip Mouse Platform

    Swivel Mouse - Mousing Platform

    The swivel mouse mounts underneath either the left or right front corner of the platform. It swivels out from underneath the keyboard platform easily and tucks out of the way when not in use. This mouse platform is available in right, left and dual configurations. The main difference between the clip mouse and swivel mouse is the adjustability. The swivel platform stays on the same tilt or angle as the keyboard tray; the clip mouse angle can be adjusted independently.

    Humanscale Swivel Mouse Platform

    M2 Mouse - Mousing Platform

    The M2 offers all the advantages of the swivel mouse, but it is slightly larger and offers a uniquely shaped platform. This lets a user bring the mousing surface closer to their body for a lower risk mousing position.

    81L M2 left

    Palm Support

    Select from two different palm rest options for your 700 keyboard tray: foam or gel. Both are covered with an easy to clean, black synthetic leather.A 19 inch slim gel palm rest with synthetic leather cover is also available for users with thin keyboards. The slim palm rest is only about a quarter of an inch thick and is available in black or silver. Slim palm rests are not compatible with swivel mouse platforms.

    Humanscale Palm Rests

    Track Length

    The track mounts to the underside of your work surface. It directs and supports the Humanscale mechanism and keyboard tray as it slides forward and back. Standard length on most mechanisms is 21 5/8 inches. That length ensures that the keyboard tray can be completely stowed under your desk when not in use. Some mechanisms come standard with a shorter or longer track. Consult each description for that information, but all systems can be ordered with any track length.


    Mouse Pad

    The Humanscale 700 Diagonal Corner Keyboard Tray can be ordered with a black mouse pad to fit any of the available mousing platforms.

    8.5'' swivel platforms MPGEL8 8.5'' gel mouse pad
