The Gezu Impex Adjustable Post Support is designed for contractors and DIY enthusiasts who require a heavy-duty, versatile solution for securing wooden posts for pergolas, decking, and fencing. Its standout feature is the dual-threaded adjustment mechanism, which allows for precise height alignment even after the initial installation. While the support is exceptionally durable and suitable for outdoor use, users must ensure they maintain the minimum thread engagement for safety, which is a critical installation detail.

This support is designed for use on solid, stable surfaces like concrete or solid timber. It is not intended to be sunk directly into loose soil.
The support is adjustable between 120 mm and 160 mm.
No, you must provide your own anchor bolts or screws suited for your specific surface material.
The support plate is 100 x 100 mm, designed for 100 mm square posts.
Yes, the dual-threaded design allows you to adjust the height even after the post has been installed, provided the structure's weight allows for minor lifting.
Ensure all four base bolts are tightened securely to the foundation and check that the internal thread engagement meets the 10-20 mm safety requirement.
Clean any construction dust or debris from the threads with a wire brush and apply a small amount of silicone-based lubricant.
To set up the support, place the base plate on your chosen surface and mark the four 13 mm holes. Secure the unit using appropriate heavy-duty masonry anchors (for concrete) or lag screws (for timber).
Installation Critical Note: For optimal safety and structural stability, ensure that approximately 10 to 20 mm of the total adjustment range remains engaged within the thread. Never extend the support to the point where the threads are loose, as this compromises the load-bearing capacity.
Care: To maintain the unit’s lifespan, periodically inspect the threads for debris or corrosion, especially in coastal or humid areas. Apply a light lubricant to the threads once a year to ensure the adjustment mechanism continues to function smoothly.
