    What are the dimensions of the underdesk mount portion?
    A shopper on Nov 24, 2017
    BEST ANSWER: Hi, the part that mounts to the underside of the desk is 18.2" x 5.4". You can click on the "Diagram" link on the bottom of the product page to see more details. Thanks for checking.
    What is the adjustable range (height) for the keyboard tray? ( It would make it easier for me if the measurements were in relation to the bottom surface of the desk, for example, the tray can be up to 1" higher or 4" below the bottom surface of the desk, but I'll take a range as well such as 5" in my example )
    Hector H on Dec 30, 2017
    BEST ANSWER: It will go level with the desk and 4" below it.
    Can anyone tell me the height of the underdesk mounted portion? The length and width is visible in the diagram but, not it's height and the desk I built has a 2" support piece that runs across the front of the underside of the desk that I want to make sure it will clear. Thank you.
    Kris A on Apr 3, 2018
    BEST ANSWER: Hi, it is approximately 1.5" high. Hope this helps.
    I notice on the manual that there is a significant component to the keyboard tray underneath the actual keyboard tray that is not visible in the diagram. How far down does this component reach? I'm wondering if my legs will be obstructed by it
    Hector H on Dec 30, 2017
    BEST ANSWER: Hi, the part under the keyboard tray itself only goes down around 3 inches at it's lowest point and slopes out of the way. It is around 4 inches wide centered on the rear part of the keyboard tray. We have uploaded a video on the product page that might give you a better idea of how this part looks like. Thanks for checking.
    Is there a positive lock on the extend/retract motion? (in other words, when fully extended, do I just push the tray to make it go under the desk or is there a locking mechanism that holds it in place until I want to stow the keyboard under the desk? )
    A shopper on Dec 30, 2017
    BEST ANSWER: Edit from last post. There is an adjustment knob to tighten.and lock in place. This is very well made compared to any other keyboard drawer that I have seen.

    Does the arm swivel a full 90*? That is, could this be mounted and used sideways?
    A shopper on Nov 24, 2017
    BEST ANSWER: Out of the box, it only goes about 45* either way (if that). The motion is limited by a simple bolt in a cut slot. It may be possible to modify so that it will do what you want.
    what are the dimensions of the platform?
    A shopper on Jul 21, 2017
    BEST ANSWER: Hi, the platform is 26.4" x 10". Thanks for asking, we'll add the product drawing and measurements shortly.

    Screws too big
    Everything went well until I went to mount the tray to the bracket. The 4 screws are too big for the non holes. Nearly stripped the heads trying to screw them in. Looks like I'll be going to the hardware store for some smaller flat head screws. Other than that it seems ok.

    Well made for the price, but doesn't fit right.
    Well, isn't it supposed to fit sit stand desk from monoprice? It doesn't.
    I had to remove two supporting cross bars from the motors, and that makes it shaky.
    The keyboard itself is ok for the price.

    Response from Monoprice
    Hi, thanks for your purchase and review. However, this product is actually meant for users with regular desks who do not have an easy way to fine tune their workstations for better fit. Since their desks are fixed and not height-adjustable, this product aims to provide a movable platform to improve their keyboard and mouse position. For sit-stand desks, the desk height should ideally be adjusted for comfortable typing/arm position and the monitor height fine-tuned with a monitor mount or stand. An alternative way to use this product with our sit-stand desks might be to put wood spacers under the desktop so this product can avoid the metal frame when mounting. I hope this helps, thanks.

    Looks great for the money.
    Looking at it in the box it looks like great quality. Unfortunately it won't go much further from there. I have the Monoprice Sit-Stand Height Adjustable Table Desk Frame Workstation, Manual Crank #15721, and this product will not fit. The cross bar on this desk base is in the way.
