- Attach Leveling Feet: Screw the leveling feet into the bottom of the lower poles. Ensure they are securely tightened.

- Install Plastic Sleeve Clips: Snap the two halves of a plastic sleeve clip around each pole at the desired height for the bottom shelf. Ensure the clips are at the same height on all four poles to keep the shelf level. The grooves on the poles indicate where the clips should be placed.
- Place Bottom Shelf: Slide the bottom wire shelf over the poles, ensuring the corners of the shelf rest securely on the plastic sleeve clips. Apply gentle downward pressure until the shelf is firmly seated.
- Install Remaining Shelves: Repeat step 3 and 4 for the remaining three shelves, adjusting the height of each shelf as needed. Ensure all clips are at the same level for each shelf.
- Final Check: Once all shelves are in place, gently push down on each corner of every shelf to ensure they are fully seated and stable. Adjust the leveling feet if the unit wobbles.

7. Troubleshooting
If you encounter any issues with your shelving unit, refer to the following common solutions:

|---|---|---|
| Shelving unit is wobbly or unstable. | Uneven floor surface; shelves not fully seated; leveling feet not adjusted. | Adjust the leveling feet until the unit is stable. Ensure all shelves are pushed down firmly onto their plastic clips. Verify the unit is on a flat surface. |
| Shelf appears to be bending or sagging. | Exceeded weight capacity for the shelf; weight not evenly distributed. | Reduce the weight on the shelf. Redistribute items to ensure even weight distribution. Ensure no single shelf exceeds 250 lbs. |
