Reorganized my office with 3 of these. Only easy "assembly" was re- attaching handles to the outside of the drawers. Only drawback is 3/4 drawer opening so file storage is cut down a bit but for the sale price a good deal.
The handles are screwed inside the drawer to prevent damage before use and one has to remove and fit handles on the outside. I cannot get the screws off as they are too tight. I have used every kind of screw. I may have to call for installation that will mean i will be charged more.
