The Gezu Impex Adjustable Bolt Down Post Support is an ideal solution for DIY enthusiasts and professionals working on garden construction projects like fencing or pergolas. Its primary benefit is the built-in threaded rod that allows for precise height adjustments, making it perfect for installations on uneven concrete or wooden foundations. While it provides excellent structural stability, users should note that they must provide their own heavy-duty anchor bolts suitable for their specific surface material.

Yes, they are suitable for bolting down to existing solid timber decks or concrete bases.
No, you will need to purchase appropriate anchor bolts based on your specific floor material.
While intended for standard garden structures like pergolas and fencing, always ensure the total load does not exceed the structural capacity of the substrate you are bolting into.
The steel is zinc flake-coated to provide high corrosion resistance for outdoor use.
It is highly recommended to set your height prior to attaching the timber post to avoid putting stress on the wood connection.
Ensure the locking nut on the threaded rod is tightened firmly against the base to prevent movement.
Verify you are using the correct drill bit type for your surface (e.g., SDS masonry bits for concrete).
Installation requires a drill, a masonry bit (if attaching to concrete), and appropriate expansion bolts. To install: 1. Position the base plate on the substrate and mark the 13 mm holes. 2. Drill the required holes for your chosen anchors. 3. Secure the base plate using high-quality fasteners. 4. Rotate the threaded support plate to your desired height. 5. Mount the timber post onto the support plate using appropriate timber screws. To maintain the life of the support, periodically check that the bolts are tight and the base is free from excessive standing water or debris that could trap moisture against the zinc flake finish.
