Important Safety Information
- Weight Capacity: Do not exceed the maximum weight limit of 150 lbs per shelf or 600 lbs for the entire unit. Ensure weight is evenly distributed across all shelves. Overloading can cause personal injury or property damage.
- Wall Mounting: Wall mounting is recommended for enhanced stability, especially when storing heavier items or in areas with potential for tipping. Wall mounting hardware is not included.
- Placement: Avoid storing the unit in direct sunlight to prevent material degradation over time.
- Assembly: Ensure all components are securely connected before placing items on the shelves.
Setup & Assembly
The IRIS USA 4-Tier Heavy Duty Plastic Storage Shelf features an integrated leg design for tool-free assembly. Follow these steps for quick and easy setup:
- Unpack Components: Carefully remove all shelves and support legs from the packaging. Ensure all parts are present. The support legs are typically packed underneath the shelves.
- First Layer Assembly: Place the bottom-most shelf on a flat, stable surface. Insert four support legs into the designated slots on the underside of this platform. Ensure they snap securely into place.
- Add Subsequent Shelves: Take the next shelf and align its corner holes with the top ends of the installed support legs. Press down firmly until the shelf clicks into place, creating a secure connection.
- Repeat for Remaining Shelves: Continue adding support legs and shelves in the same manner until all four tiers are assembled.
- Final Check: Once assembled, gently push down on each corner of every shelf to confirm all connections are secure and the unit is stable.
