4. Setup and Assembly
The ONBRILL H1 Plus closet system features a smart thread-to-thread connection design for quick and secure assembly without specialized tools. Follow these steps carefully:
- Prepare the Area: Choose your desired installation location. Ensure the wall is structurally sound and clear of electrical wires or plumbing. You will need an assembly space with a minimum height of 7'6" (88.6 inches).
- Assemble Vertical Pipes: Connect the vertical pipe sections by screwing them together using the thread-to-thread design. Ensure all connections are tight.
- Attach Wall Mounting Brackets: Secure the wall mounting brackets to the top and middle sections of the vertical pipes.
- Mark Wall Positions: Hold the assembled vertical structure against the wall at the desired height. Use a level to ensure it is straight. Mark the positions for drilling the wall anchors.
- Install Wall Anchors: Drill pilot holes at the marked positions. Insert the appropriate wall anchors for your wall type (drywall, concrete, hollow wall, or tile).
- Mount the System: Securely attach the vertical pipes with brackets to the installed wall anchors.
- Install Shelves: Attach the plastic clips to the vertical pipes at your desired shelf heights. Ensure the arrows on the clips point upwards and they are securely slotted into the grooves. Place the expandable wire shelves onto these clips. Ensure the mesh direction is proper for stability.

7. Troubleshooting
If you encounter any issues with your ONBRILL H1 Plus closet system, refer to the following common problems and solutions:
