Setup & Assembly Instructions
The Metallitrend 4-Tier Industrial Shelving features a tool-free assembly with a boltless keyhole system. A rubber mallet and gloves are provided to assist with the process.
- Prepare the Workspace: Clear a flat, level surface for assembly. Ensure adequate space around the unit.
- Attach Foot Protectors: Take four of the upright posts. Attach a plastic foot protector to one end of each post. Ensure the wider opening of the post is at the top for proper brace insertion.
- Assemble the Base Frame: Connect two long horizontal crossbeams to two upright posts using the keyhole system. Ensure the lip on the crossbeams faces upward to support the shelf panel. Lightly tap with the rubber mallet to secure the connections. Repeat for the other two upright posts and two long crossbeams.
- Connect Short Crossbeams: Attach two short horizontal crossbeams between the two assembled long sides, forming a rectangular base. Ensure all connections are secure.
- Insert First Shelf Panel: Carefully slide the first steel shelf panel into the frame, resting it on the upward-facing lips of the crossbeams.
- Build Subsequent Tiers: Continue adding upright posts and horizontal crossbeams for the next tiers. Ensure the wider opening of the upright posts is always facing upwards. Use the rubber mallet to firmly secure each connection.
- Insert Remaining Shelf Panels: After each tier's frame is complete, insert the steel shelf panel.
- Finalize Assembly: Once all tiers are assembled, ensure all connections are tight and the unit is stable.

Operating Instructions
- Adjustable Shelf Height: The shelves can be adjusted to different heights to accommodate various items. To adjust, carefully remove the shelf panel, detach the horizontal crossbeams from the upright posts, reposition them to the desired height using the keyhole system, and then reinsert the shelf panel.
- Convertible Design: This shelving unit can be effortlessly split into two freestanding smaller units. To do this, separate the upright posts at the middle connection point and assemble two independent units following the basic assembly steps.
- Weight Distribution: Always distribute weight evenly across the shelves. Avoid placing excessively heavy items on one side or corner.

Maintenance
- Cleaning: The all-steel laminate shelves are moisture-resistant and easy to clean. Wipe down with a damp cloth and mild detergent as needed. Avoid abrasive cleaners that may damage the finish.
- Regular Inspection: Periodically check all connections to ensure they remain secure. Tighten any loose connections by tapping with the rubber mallet. Inspect for any signs of wear or damage and address them promptly.
- Rust Prevention: While the steel is designed to be moisture-resistant, avoid prolonged exposure to excessive moisture to prevent rust.

Troubleshooting
- Difficulty during Assembly: If parts are difficult to fit, ensure they are correctly aligned with the keyhole system. Use the provided rubber mallet to gently tap components into place. Avoid excessive force that could bend or damage parts.
- Wobbling or Instability: Ensure all horizontal crossbeams are fully seated into the upright posts. Re-tap all connections with the rubber mallet. Verify the unit is on a flat, level surface. For maximum stability, especially with heavy loads, consider anchoring the unit to a wall.
- Bent Components: While the steel is sturdy, improper handling or excessive force during assembly can cause bending. If a component is significantly bent and affects assembly or stability, contact customer service for assistance.
