The DE200-250 option was too small for the corner of the desk, leaving a gap. The DE400-450 solved all our problems- looks and fits great!
Extended my desk area perfectly
I believe this is the best corner sleeve on the market. It is a little pricey, but I think it is worth the extra. Large size helps it cove worksurface joints easily.
This simple device extends the cube surface without all the knobs and levers that are always slipping on the "ergonomic" keyboard trays.
