how does this mount to the desk?

It has a metal plate that attaches to the unit and then screws to the desk. See this picture http://beatstruggles.com/wp-content/uploads/2013/05/IMG_3510-1024x682.jpg and this one http://ecx.images-amazon.com/images/I/41B2ST8mIgL._SY300_.jpg

It clamps around one of the edges and you screw tighten a bolt on the bottom.

There is a c- clamp type for the edge of the desk. Or it has another mount if you want to drill into your desk for a better position. Comes with both. Works great on the edge, that is how I use it.

The PSA1 has two bases - both of which mount to a desk or table. The primary mounting base is a tapered cylinder with a hole in its top for the boom. Dropping down from one of its edges is a C-clamp that mounts to the protruding edge of a horizontal surface like a table or desk. The clamp has a fairly wide opening of about 3 inches so it can easily accommodate a wide range of flat surfaces. It has an alternate base that is a grommet-like affair that mounts in a hole you drill into a desk or table. The boom arm then has an axle that protrudes from its bottom which slides into the hole in the top of either base. The boom arm is held in the base by gravity alone so hanging the mount from the ceiling will not work. The simplicity of the base requires that it be mounted on a level surface. On a tilted surface, the weight of the boom arm and the lack of any clamps or screws to impede rotation would cause the entire unit to turn as it seeks the lowest side. Hope that helps.

Either a clamp (which opens up to 3 inches) or permanent hole drilled into desk/table. Hardware for both options included. I use the clamp.

Mine came with both a C clamp and a mount to be fastened to the desk with screws. I'm using the C clamp and it works well.

It comes with an attachment that goes under desk but yes it does require drilling through your desk and attaching with bolt. However, I did not mount mine, its very sturdy at the base.

I am not sure as both my desks already had holes in them for cords and such, but here is what I found on their website:Mounting Options: Desk Clamp attaches to surface edge .4" to 2.4" (10 to 60 mm) thick; Grommet Mount attaches through surface holes .31" to 2" (8 to 50 mm) wide and up to 3" (76 mm) thick http://www.ergotron.com/ProductsDetails/tabid/65/PRDID/523/language/en-US/Default.aspx

Mine is hanging over my desk, secured with push pins (as is). What else would you do with it?

there is a rubber or plastic tweaser like inside the two sliding rails , pinch them togethere and the rail will slide out from its track ,take the track and mount it to the desk frame arms below the desks table top then take the other track with the tweaser like rubber, bolt them on to the desktray board and then take the rubber or plastic tweaser looking things on the track insert you have bolted on the tray pinch them together and slide them on to the track you mounted on the desk frame that should be it your done

You can customize where you mount it but it recommended mounting at least 1" of space back from the front edge of the desk. So long as there is enough room for the bracket you will be fine, just use the bracket as a guide to where exactly you want it and you can stick it there (the piece has a strong adhesive which allows you some freedom to work) and then you just put the screws in and compete setup and viola!

There is a plate connector that fits under the desk and is screwed up into the desk. If your desk has a lip that extends down from the top, you will have to add a filler strip like a piece of plywood under the desk. It is pretty easy to attach. It is very solid and weighs more than other keyboard trays, but that is a big plus.

I don't think so, but I have never tried to mount mine because I have an office desk. I hope this helps you.

Suggest you use make a template for screw hole position (unless you have help holding the tray) then use an ice pick to make a starter hole in the bottom of desk for the mount.

It uses two L brackets on the back to attach to any desk that is of equivalent or greater width. It is designed to also rest its back against the wall. If you are going for a free-standing unit, I recommend buying a second set of L brackets to bolt down the front. That is what I did.I now have a free-standing desk and hutch, and the hutch is bolted down nice and secure with my modifications.

My desktop is mounted inside of a drawer. I pull it out when I need it and push it in when it is not needed. Earlier, I had it setting on the desk with my computer on top of it. This worked just fine also. If you extend it out very far, you need to support it someway in the back so it doesn't drop into your lap with the weight from the keyboard.

It has a clap that tightens using a screw. You can use your hand. It is hard to describe, But it is a very solid base. If you are clamping it to a desk. You will need about 2 inches for it to fit properly.

The top of the desk is attached by four bolts from underneath. The bolts are easily accessible and will allow you to move both pieces of the desk and then re-attach the top in a matter of minutes.

It is a stand-alone unit. Does not have to be attached to desk. Heavy enough that it doesn't shift around. It also has rubberized pads on the bottom to keep it in place.

The corner mounts have 3 slots to choose from to hold the tray in place. You can either be right up against the bottom of your desk or a little below or like myself at the bottom so the mouse pad can stay extended all the time even when the drawer is closed under the desk.

At a visual estimate, about 5inches long by 2 inches wide by 5 inches deep (if you include the backplate), there are also massive eyelet screws hanging out the bottom. I love this thing, but it does have a pretty set way to mount it to the edge of a desk. Not sure how you would pass it through a hole on your desk, or what you expect to clip it to underneath the desk.However, it is probably easy enough to wedge through a tight fitting desk edge against a cubical wall, and still clamp on correctly.
