Drawer removal directions:
Each side of the glide features a small release lever—one positioned to move upward and the other downward. To remove the drawer, first pull it out fully until it stops. Then, locate the two tabs on either side: one on the left (see Picture 1) and one on the right (see Picture 2).
Next, press upward on the left tab (Picture 3) while simultaneously pressing downward on the right tab (Picture 4). With both tabs engaged, the drawer will release and can be pulled out completely.
