How to fit drawer runners

Drawer runners come in two halves: one fixed inside the cabinet and one on the drawer. They have handed left and right parts and must sit parallel and level. Most sticking or drooping drawers come down to runners that are reversed, misaligned or screwed into the wrong holes.

Tools needed

  • Cross-head screwdriver
  • Tape measure
  • Pencil
  • Try square or spacer block

Parts to check first

Before you start, lay everything out on a soft surface (the flattened box works) and check it against the parts list in your manual.

  • Cabinet runners, left and right
  • Drawer runners, left and right
  • Short screws for the runners
  • Drawer box

Step by step

  1. Step 1: Separate the runner halves and mark each one L or R; the manual usually shows a letter or a stop at the front end.

  2. Step 2: Screw the cabinet runners to the carcass sides with the front edge set back by the distance the manual gives, using the pre-drilled holes.

  3. Step 3: Measure from the bottom of the carcass to each runner at front and back to confirm both sides are at the same height and level.

  4. Step 4: Fix the drawer runners to the drawer sides, lining them up with the bottom edge of the drawer or the marked holes.

  5. Step 5: Slide the drawer in so the wheels or ball bearings drop into the cabinet runners, and push it until it closes against the stop.

  6. Step 6: If the drawer rubs or drops, check left and right have not been swapped, then adjust using the slotted holes before tightening.

Common mistakes

  • Swapping left and right runners, so the drawer will not engage.
  • Using long screws that break through the outside of a thin carcass panel.
  • Fixing one side higher than the other, so the drawer runs crooked.

Safety notes

  • Heavy drawers on full-extension runners can pull a cabinet forwards; anchor it to the wall.
  • Keep fingers clear of ball-bearing runners when closing them.
