Why Drawer Slide Installation Matters
Tools You Actually Need
- Side-mount drawer slides (length = drawer side minus ½ in)
- #8 screws
- Drill + ⅛ in bit
- Level, tape, pencil
- Spacer block the thickness of your drawer face
Step 1 – Know the Two Halves
Every side-mount drawer slide has a cabinet member and a drawer member. Mix them up and the lever won’t click. Label each half before you install drawer slides or you’ll be drilling new holes twice.

Step 2 – Mount the Drawer Member
Step 3 – Pop the Lever
Press the plastic tab to detach the drawer half. Now you can install the cabinet member without the drawer flopping around like a cat in a bathtub. Re-attach after the cabinet half is locked.

Step 4 – Use a Spacer Block for Inset Faces
Clamp a dummy front to the cabinet. Rest the cabinet member on the spacer so the drawer slides sit exactly where the real face will live. This trick guarantees flush, gap-free drawer slide installation every time.

Step 5 – Level, Screw, Test
Butt the cabinet member to the spacer, level it, and sink one screw in the front horizontal slot. Check level again, then add rear and middle screws. Slide the drawer half on and test. Smooth? Tighten every screw. Rough? Nudge the drawer slides sideways in the slots until the reveal is razor-line perfect.
