Shimming the drawer slides will ensure that your drawer operates smoothly and prevents it from getting stuck. So Keep Reading to find out How to Shim Drawer Slides.
Summary: Shim drawer slides are a great way to keep your drawers organized and tidy. Follow these simple steps to create your own: 1) Mark the location of each drawer on the bottom of the slide. 2) Measure the depth of the drawer and subtract 1/2 inch from the measurement. This will be the thickness of the shim. 3) Cut the shim to the desired length and attach it to the bottom of the drawer slide with double-sided tape. 4) Slide the drawer into the slide and secure it with the tape.

What Causes You Shim Drawer Slides?
The most common reason to shim drawer slides is that the slide itself has become misaligned. This can happen over time as the result of normal wear and tear. Another reason you might need to shim your drawer slides is if the drawer box has become misaligned. This can happen if the drawer box is not mounted correctly or if it has been damaged. If the drawer box is misaligned, the drawer slides will not be able to operate correctly.
Why Are My Drawers Uneven?
There are several reasons why your drawers may be uneven. The most common reasons are:
1. Slides Are Not Installed Correctly
If your slides are not installed correctly, they will not be able to support the weight of the drawer properly. This can cause the drawer to become unbalanced and uneven. Slides should be installed so that they are level and evenly spaced. If your slides are not installed correctly, you will need to uninstall and reinstall them.
2. Drawer Box Is Not Mounted Correctly
If the drawer box is not mounted correctly, it can cause the drawer slides to bind. The drawer box should be mounted so that the top of the box is level with the top of the cabinet opening. If it is not, shims can be used to level it.

3. Drawer Box Is Damaged
If the drawer box is damaged, it will not be able to support the drawer’s weight properly. This can cause the drawer to become unbalanced and uneven. The drawer box should be replaced if it is damaged.
4. Drawer Slides Are Worn Out
If the drawer slides are worn out, they will not be able to provide the support that is necessary for the drawer to function properly. Worn-out drawer slides can be replaced with new ones, or they can be shimmed.
5. Cabinet Is Not Square
If the cabinet is not square, the drawer slides will not be able to operate properly. The cabinet should be squared up before the drawer slides are installed. If the cabinet is not square, shims can be used to level it.
6. Cabinet Is Damaged
If the cabinet is damaged, it can cause the drawer slides to bind. The cabinet may need to be repaired or replaced. If the drawer slides are damaged, they will need to be replaced.
7. Something Is Blocking The Drawer
If something is blocking the drawer, it will not be able to open or close properly. Make sure that nothing is blocking the drawer before you try to open or close it.
8. The Drawer Is Overloaded
If the drawer is overloaded, it will not be able to open or close properly. Do not overload the drawer. Try to distribute the weight of the contents inside the drawer evenly.

9. The Slides Are Dirty
If the slides are dirty, they will not be able to operate properly. Clean the slides with a clean, dry cloth. Do not use any cleaners or solvents on the slides.
10. The Latch Is Not Engaging Properly
If the latch is not engaging properly, the drawer will not be able to stay closed. Make sure that the latch is properly engaged before you try to close the drawer.

Step by Step How to Shim Drawer Slides
1. Remove the Drawer From the Cabinet:
The first step is to remove the drawer from the cabinet. This will allow you to access the drawer slides. Next, use a screwdriver to remove the screws that are holding the drawer in place. If your drawer has knobs or handles, you will need to remove them before you can remove the drawer.
2. Inspect the Drawer Slides:
Once the drawer is removed, you can now access the drawer slides. First, inspect the slides to see if they are damaged or misaligned. If the slides are damaged, you will need to replace them. If the slides are only misaligned, you can try to adjust them back into place.
3. Measure the Gap Between the Slide and the Drawer Box:
The next step is to measure the gap between the drawer slide and the drawer box. This will help you determine how much shimming is required. Use a tape measure to measure the gap between the slide and the drawer box. You will not need to shim the slides if the gap is less than 1/8 inch.

4. Cut the Shim:
Once you have determined how much shimming is required, you can now cut the shims. Shims are thin wood pieces that fill the gap between the slide and the drawer box. You can purchase shims at your local hardware store. Cut the shims to size using a saw. If you are shimming more than one drawer, you will need to cut multiple shims.
5. Remove the Drawer Slide:
The next step is to remove the drawer slide. This will allow you to install the shims. Next, use a screwdriver to remove the screws that are holding the drawer slide in place. Once the screws are removed, you can now pull the drawer slide out.
6. Use a Level:
Before you install the shims, you will need to use a level. This will ensure that the shims are installed correctly. Place the level on the shims and make sure that they are level. If the shims are not level, the drawer will not operate correctly.
7. Install the Shims:
The next step is to install the shims. Insert the shims into the gap between the slide and the drawer box. Make sure that the shims are inserted snugly and that there is no gap between the shims and the slide. If there is a gap, the shims will not be effective.
8. Re-Install the Drawer Slide:
Once the shims are in place, you can now re-install the drawer slide. Use a screwdriver or a power drill to screw the screws back in. Be careful not to over-tighten the screws, as this may strip the hole or damage the shims.
9. Adjust the Screws on the Bottom:
The next step is to adjust the screws on the bottom of the drawer. These screws are used to adjust the height of the drawer. If your drawer is too high or too low, you can use these screws to adjust it. If the drawer is too high, turn the screws clockwise. If the drawer is too low, turn the screws counter-clockwise.
10. Test the Drawer:
Once you have finished shimming the drawer, you can now test it. First, close the drawer and make sure that it is level. Also, ensure that the drawer is not too tight or loose. You may need to adjust the shims again if the drawer is not closing properly. Finally, check to see if the drawer is aligned with the rest of the cabinets. If it is not, you may need to adjust the shims again or use a different type of shim.
How Do You Fix an Uneven Drawer Slide Without Shim?
If your drawer slide is uneven, you can try to adjust it back into place. To do this, you will need to remove the screws that are holding the drawer slide in place. Once the screws are removed, you can now adjust the drawer slide. To make the drawer slide higher, turn the screws clockwise. To make the drawer slide lower, turn the screws counter-clockwise. You may need to experiment with the screws to find the right adjustment. Once the drawer slide is in the correct position, you can now re-install the screws.
