Older dressers typically used wooden runners that wear out because of constant use over the years, but that's no reason to give up on that old dresser -- it's probably built better than a new one. This type of runner is basic and not that difficult to make, repair and install. If you want to update it to a metal runner, it's a relatively simple procedure.
Most dressers have a thin plywood back. The runners are supported by horizontal braces or stretchers on the inside. Remove the back from the dresser to facilitate a repair job. The plywood is held in place by screws or nails. Remove them and lift off the back to reveal the braces.
Before you get too enthusiastic about replacing an old runner, check to see if it needs to be replaced. It might be that the runner is loose. A few surgically placed screws should secure it.
Repairing Splits or Cracks
If a wooden runner is split or cracked, remove the screws or nails holding it in place.
Inject glue into cracks or splits and add clamps.
When it's dry, reinstall it. Check the runners on the drawer too, and repair them as needed.
Make a New One
If the runner is too far gone to repair, make a new one. This type of runner is typically nothing more than a dado or rabbet, which is a slot or channel in a piece of wood. The channeled runner might be on the drawer, or on the dresser. The opposing slide has a matching piece that glides inside the channel. Install a dado blade on a table saw and reproduce the channel on the runner. Optionally, take the drawer to a cabinet shop and have a professional make you one.
Installing New Wooden Runners
Wooden runners install with screws or nails from the front and back. It's advisable to reinstall them with screws.
Cut it to length, and drill some pilot holes.
Fit the runner on the drawer, and place the drawer back into the dresser.
Have an assistant hold the drawer in place while you mark the locations of the runner from the back, or if possible, screw it on. This ensures that it's in the right place.
Gently remove the drawer and reinforce the runner with more screws.
If you decide to update older wooden runners with contemporary metal runners, there are three types: under-mount, side-mount and center-mount (or bottom-mount). Under-mount runners are the best choice for older dressers. They fasten to the side of the drawer box and have a ledge that fits under the bottom edge of each side of the box.
- More adaptable to older dressers.
- Wide tolerance for installation.
- Supports a moderate amount of weight.
- Requires close tolerance between drawer and dresser.
- Requires flush-mounted jambs. Most dressers don't have them.
- High weight capacity.
- More expensive than other types of runners.
- Harder to install than center-mount.
- Somewhat flimsy, allowing drawers to move from side to side.
- Won't support as much weight as other runners.
Installing Under-Mount Runners
Measure for length: Choose your runner by first measuring from the front, horizontal support, to the horizontal support in the back. Metal runners are available in different lengths, so choose one that's long enough. Screws for runners are included in the kit.
Install the drawer runners: Metal runners -- slides -- are sold in pairs. The slides are stamped "CR," "CL," "DR" and "DL," for cabinet right/left and drawer right/left. Screw the slide marked "DR" to the bottom, right side of the drawer. The "DL" slide fits on the left side.
Install the dresser runners: Measure the locations of the two runners, and transfer them to the horizontal support on the front of the dresser. Screw the slide marked "CR" to the right side. Screw the slide marked "CL" to the left side. Use the oval-shaped holes in the slides. The oval-shaped holes allow you to adjust the slide later.
Insert the drawer into the dresser, matching the rollers on drawer slides with the slots on the dresser slides. Screw the back of the slides to the supports from the back of the dresser, using the oval-shaped holes in the slides.
Slide the drawer in and out of the dresser. If it sticks, rubs or is hard to move, loosen the screws in the oval-shaped holes, tap them in the direction needed, and test the drawer. When it moves smoothly, remove the drawer, and install screws in the remaining holes.
