The latches are set near the back end of the metal drawer slides, so pull the drawer out as far as possible in order to access them.
Sometimes, slides are mounted underneath the drawer, so check there if your drawer doesn’t have side-mounted slides. You may need to press down clips located on the slide tracks to unlock them. These will come off when you unscrew the slides.
For an under-mount slide, measure the length of the drawer and use that measurement for your slide.
Some slides offer special motion features like automatic self-close or opening with a simple push.
Drawer slide jigs work on all types of cabinets, including those without face frames.
The jig keeps the sliding frame bracket level, but if you’re not using one, you can use a level to check that the bracket is even. If you are using under-mount or center mount slides, place the frame pieces on the cabinet’s bottom.
Avoid overtightening the screws or you could damage the cabinet.
If your drawer isn’t heavy, you might be able to get away with using just 1 jig. However, if the drawer is heavy, it’s best to work with 2 jigs.
At this point, you can check to see that the drawer glides smoothly. Push the drawer in to see if it comes to a gentle stop within the cabinet. If it does, great—extend the drawer and the drawer slides back out. If it doesn’t, re-adjust the drawer slides and try again. If you’re attaching under-mount slides, set the drawer onto the drawer slides so the right and left sides of the drawer completely hide the slides.
Avoid overtightening the screws, or you might drill through the drawer.
