Drawer slides are the tiny rails that make or break your build. Mess them up and you’ll hear screech, see sag, feel wobble. Nail the install and the drawer vanishes—only silk-smooth motion remains. This guide shows how to install drawer slides the right way, using only a drill, a level, and a scrap block. Read once, build forever.

Why Drawer Slide Installation Matters

Bad drawer slide installation wastes wood, time, and sanity. Crooked side-mount drawer slides bind, gouge, and eventually snap. Correctly installed drawer slides carry the load, close soft, and self-clean. If you want furniture that feels store-bought, start with perfect drawer slides.

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
That’s it. No CNC, no lasers.

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

Lay the drawer on its side. Park the drawer member 1 in behind the drawer front, parallel to the bottom. Pre-drill, then drive two screws into the horizontal slots only snug—this lets you adjust the drawer slides later.

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.

Face-Palm Mistakes When You Install Drawer Slides

❌ Swapping cabinet and drawer members—levers won’t latch.
❌ Skipping spacer blocks—inset faces end up proud.
❌ Overtightening screws—particleboard blows out and you’re relocating holes.
❌ Ignoring level—drawer slides tilt, drawer screeches, beer spills.

  2. Screw drawer member to drawer.
  3. Detach lever.
