Assembly is straightforward but involves numerous screws. It is recommended to have two people for certain steps, though one person can complete it. Allow approximately 1-2 hours for initial assembly.
Step-by-Step Guide
- Unpack Components: Carefully remove all parts from the packaging. Inspect for any damage. Keep all packing materials until assembly is complete.
- Install Leveling Feet: Before attaching the base to the sides, install the leveling feet onto the bottom panel. This can simplify later adjustments.
- Assemble Cabinet Frame: Connect the side panels to the bottom and top panels using the provided hardware. Ensure all holes align correctly. The design features strong gussets and pre-threaded bolt holes for secure connections.
- Attach Back Panels: Secure the four back panels to the cabinet frame.
- Install Doors: Attach the two stainless steel doors. The doors are designed to be installed in two pieces. Ensure proper alignment for smooth operation.
- Install Handles and Lock: Secure the recessed handles and the lock mechanism to the doors. Test the lock with the provided keys.
- Insert Shelves: Place the three adjustable steel shelves into the desired positions. The shelves can be adjusted at 1-inch increments.
- Secure to Wall (Optional but Recommended): Use the included wall mounting straps to anchor the cabinet to a wall for enhanced stability and safety, especially in high-traffic areas or if the cabinet will hold heavy items.
Tip for Plastic Fasteners: If your model includes plastic fasteners, a surgical hemostat can be used to grip the shank under the top button while lightly tapping with a hammer to lock them in place. This prevents bending or breaking.

5. Maintenance
To maintain the appearance and longevity of your storage cabinet:
- Cleaning: Wipe surfaces with a damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the finish or the UltraGuard fingerprint-resistant coating on the doors.
- Inspection: Periodically check all screws and connections to ensure they remain tight. Re-tighten if necessary.
- Door Alignment: If doors become misaligned, gently adjust the hinges or re-tighten hinge screws to restore proper closure.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Cabinet is wobbly or unstable. | Uneven floor; leveling feet not adjusted; wall straps not installed. | Adjust the leveling feet until the cabinet is stable. Install wall mounting straps to secure the cabinet to a wall. |
| Doors do not close properly or are misaligned. | Hinges are loose or misaligned; cabinet frame is not square. | Check and tighten hinge screws. Ensure the cabinet frame is assembled squarely. Adjust leveling feet if the floor is uneven. |
| Lock mechanism is stiff or not engaging. | New lock; debris in mechanism. | Apply a small amount of graphite lubricant to the key and insert into the lock several times. Ensure the doors are fully closed when attempting to lock. |
