2. Move the inner rail of the drawer slide away from the edge of the drawer, we find that there will be a spring at the back, we just need to press gently on both sides to remove the inner rail. Also note that the outer and center rails are attached to each other and it is impossible to separate them.
3. First install the outer and middle rails on both sides of the drawer box, then fix the inner inverted frame on the side of the drawer (pay attention to the outer and inner rails should be aligned, otherwise the drawer at the back won't fit). If it is a one-click finish furniture, there is a hole in the drawer cabinet and the side of the drawer, it is very good to install, no need to re-find the place, instead of the finish you have to punch the holes by yourself.
4. Before installing the slides, the first thing you need to do is to assemble the drawers as a whole, there are two holes in the rails, you can adjust the spacing of the drawers up and down and front and back.
5. The next step is the installation of the inner and outer rails, at this time the inner and outer rails are in the same position, with screws to fix the inner rails to the drawer cabinet. Then we fixed the remaining unlocked screws.
6. The other side is used in the same way (emphasizing that the inner rails on both sides must be kept horizontal).
7. After installation, pull a few more drawers to see if it works, if there is any problem, you can readjust.
