Thanks Shabby but i did but didn't find any information on the various sizes.

Perhaps Lily Gahagan can provide me with the information on the various sizes.

You can click on the link at the bottom of the page that takes you to "room and board" website and from there u can find the product page with all the details. Hope this is helpful : )

Well this is neat! We're getting computer desks towards end of May, they come with a little whole to manage the cords.
