3. Package Contents
Before beginning assembly, verify that all parts listed in the packing list are present and undamaged. Refer to the detailed parts list provided in the separate assembly instructions manual included with your shed for a complete inventory.
4. Setup and Assembly
The Keter Factor 6x3 shed is designed for straightforward assembly. While it can be assembled by one person, having a second person can significantly ease the process, especially when handling larger panels or the roof.
4.1 Site Preparation
A level foundation is critical for proper assembly and long-term stability. Keter recommends a concrete foundation for best stability, but a level foundation of gravel, wood, or dirt is also acceptable. Ensure the chosen site allows for the shed's external dimensions of 70 inches (W) x 44.5 inches (D) x 82 inches (H).

4.2 Assembly Steps
Follow the step-by-step instructions provided in the dedicated assembly manual. Key steps typically include:
- Base Assembly: Securely assemble the floor panel on your prepared level foundation.
- Wall Panel Installation: Attach the wall panels, ensuring they align correctly. A rubber mallet may be useful for gently tapping components into place.
- Roof Structure: Assemble the roof frame and panels. The shed features a skylight for natural light and vents for air circulation.
- Door Installation: Install the wide double doors, ensuring smooth operation and proper alignment for the lockable latch.
- Finishing Touches: Install any additional features like shelving brackets (shelves not included) and ensure all connections are secure.
