4. Setup and Installation
The Deckit Adjustable Deck Support Bases are designed for tool-free, easy installation. Follow these steps for optimal setup:
- Placement: Place the deck supports on your prepared surface with the recommended spacing. For this deck support bracket, the recommended installation spacing is 16–18 inches.
- Joist Insertion: Slide your wooden beams (joists) into the slots on top of the deck support bases. These bases are suitable for joist specifications of 2x4 or 2x6. For easier installation, please use straight wooden beams.
- Height Adjustment: Rotate the top part of the support base to adjust the height. Use a spirit level to ensure the joist is perfectly level. The dual-leveling seats allow for precise adjustments to compensate for uneven ground.
- Secure Joists: Once the desired height and level are achieved, tighten the fastener on the support to fix it in place. Then, use the provided self-tapping screws and screwdriver to secure the joists to the deck supports.

5. Operating Instructions
The primary operation of the Deckit Adjustable Deck Support Bases involves their height adjustment mechanism. Once installed, the bases allow for fine-tuning of the deck's level even after initial placement.
- Adjusting Height: To adjust the height, simply rotate the top plate of the support base. Turning it clockwise will lower the joist, and counter-clockwise will raise it. This allows for precise leveling of your deck surface.
- Post-Installation Leveling: The design enables continuous leveling adjustments, which is particularly useful if the ground settles over time. Always use a spirit level to verify the deck's evenness during and after adjustments.
6. Maintenance
The Deckit Adjustable Deck Support Bases are designed for minimal maintenance due to their durable construction materials.
- Material Durability: Made from UV-resistant polypropylene, these bases are inherently rust-proof and resistant to fading. This eliminates the need for painting, sealing, or rust treatment.
- Ventilation and Drainage: The design of the bases promotes air circulation beneath the deck and allows for efficient water drainage. This prevents moisture buildup, which is a common cause of rot and decay in traditional deck structures, thereby extending the lifespan of your wooden beams and reducing overall maintenance.
- Periodic Inspection: While low-maintenance, it is recommended to periodically inspect the bases and joists for any signs of wear, damage, or significant ground settlement. Re-leveling can be done as needed by adjusting the bases.
7. Troubleshooting
While Deckit Adjustable Deck Support Bases are designed for reliability, here are some common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Deck surface is uneven. | Incorrect initial height adjustment or ground settlement. | Re-adjust the height of individual bases by rotating the top plate until the joist is level. Use a spirit level for accuracy. |
| Bases feel unstable. | Improper placement on soft or loose ground; joists not securely fastened. | Ensure bases are placed on a firm, compacted surface. Verify that joists are properly seated and securely screwed into the base's top plate. |
| Water pooling under deck. | Insufficient slope for drainage or blocked drainage paths. | Ensure the ground beneath the deck has a slight slope away from any structures. Check that the bases' design allows for clear water flow and that no debris is obstructing drainage. |
