Assembly Instructions
The IRIS USA 5-Tier Plastic Storage Shelves feature a tool-free assembly process. Follow these steps for quick and easy setup:
- Step 1: Prepare the First Shelf
Place one shelf panel on a flat, stable surface. Ensure the underside of the shelf is facing upwards. - Step 2: Attach Legs to the First Shelf
Take four support legs. Align each leg with the designated slots on the corners of the first shelf panel. Firmly push each leg into place until it snaps securely. - Step 3: Add Subsequent Shelves
Once the legs are attached to the first shelf, place the next shelf panel on top of the installed legs. Align the leg openings of the new shelf with the top of the legs from the previous tier. Press down firmly until the shelf locks into place. - Step 4: Repeat for Remaining Shelves
Continue adding the remaining shelf panels and support legs in the same manner until all five tiers are assembled. - Step 5: Final Check
Once all shelves are assembled, gently rock the unit to ensure all connections are secure and the shelf is stable.

Care and Maintenance
To keep your IRIS USA storage shelves in optimal condition:

- Inspection: Periodically check all leg connections to ensure they remain secure.
Troubleshooting
If you encounter issues with your shelving unit, consider the following:
- Instability: If the unit feels wobbly, ensure it is placed on a level surface. Re-check all leg connections to confirm they are fully snapped into place. Applying firm pressure or a rubber mallet during assembly can help secure connections.
- Damaged Components: In rare cases, components may arrive damaged due to shipping. If you receive damaged parts, contact customer support for assistance.
- Overloading: Exceeding the stated weight capacity per shelf or for the entire unit can lead to instability or damage. Redistribute items to stay within limits.
