I was about to put a 20 year old IKEA dresser (white chipboard) on the bedside table because three of the four drawers didn't work due to broken rails. I knew IKEA didn't offer the replacement parts I needed. But my daughter didn't want to give it up (it's been in her bedroom since she was a child, and the chest of drawers still looked good except for the hanging open drawers it has :) So on a whim I decided to try Revain. Thank God! These rails fit perfectly in the grooves of the drawers! It was also very handy that the screws were included - after finding them on Revain I compared prices to other suppliers and this was the only place I found that the rails were sold as a screw kit, which is what the ended up being cheaper. The rails are about an inch shorter than my original ones, but the only issue that caused it was my own installation error, which I'll mention here in case someone else like me isn't thinking about proper placement. I centered the new rails where the originals were, but I had to place them so that the end at the front of the bureau was in the exact same place as the end of the original rail. As a result of my mistake, with all the drawers pushed in as far as possible, the drawers I attached now slide back about 1/2 inch further (offset from the front of the office) than a single drawer. I didn't have to fix it (solution: don't push drawers all the way in!)
