Open up the cabinet that you want to install a drawer in. On the inside of the cabinet, draw a line with the pencil on both walls 3/4 of an inch above the floor. Mark a point on both lines 3/4 of an inch from the front of the cabinet.
Place the slide in the location you have marked. Find the back holes on the slide for the mounting screws and mark the locations. Mark the locations of the holes on the front of the slide. Remove the slide and drill holes where you have marked.
Replace the slide in the location you have marked and use the drill to insert the mounting screws into the holes on both the slide and the cabinets. These screws will lock the slide in place and prevent it from moving while using the drawer.
Use the power saw to cut your drawer so that it is 1/8 of an inch narrower than the distance between the slides in the cabinet. Place the drawer inside the cabinet and rest it on the tabs on the front and back of the slides. Mark the position of the holes on the tabs on the bottom of the drawer.
Drill holes in the underside of the drawer where you have marked. Replace the drawer on the tabs on the slides and use the drill to insert mounting screws into the holes. This will mount the drawer to the slides.
