## Summary description

The Koelner D-TU-101 is a bolt-down post support designed for stable and secure mounting of wooden posts to concrete surfaces. With a 101 mm diameter, this durable steel support provides reliable structural integrity for fences, pergolas, and garden structures. Its bolt-down design allows for easy installation, ensuring the post remains elevated from the ground to prevent moisture damage and decay.

## Long description

The Koelner D-TU-101 Bolt-Down Post Support 101 mm is a robust mounting solution engineered for the secure installation of wooden posts onto concrete foundations. This support features a durable steel construction that ensures long-term stability for various outdoor timber structures. By elevating the post above the ground surface, the design effectively minimizes direct contact with moisture, which helps to prevent rot and decay, thereby extending the lifespan of the wooden elements.
Advantages
The primary benefit of this post support is its high-strength steel build, which provides excellent load-bearing capacity and structural rigidity. The bolt-down mechanism simplifies the installation process, allowing for precise alignment and firm attachment to concrete bases using standard anchors. Its design is specifically focused on durability and protection, ensuring that the base of the wooden post remains dry and well-ventilated, which is essential for maintaining the integrity of outdoor installations over time.
Suitable for
Installation of wooden fence posts
Construction of garden pergolas
Support for timber gazebos
Mounting posts for small garden structures
This post support is not intended for use on soft or unstable ground surfaces such as soil or sand, as it requires a solid concrete foundation for secure anchoring. It is also not suitable for applications involving extremely heavy structural loads that exceed the technical specifications of the steel bracket.
Key specifications
Diameter: 101 mm
Material: Durable steel
Mounting type: Bolt-down
Application: Concrete surfaces
To install the support, first mark the desired position on the concrete surface and drill holes corresponding to the base plate openings. Secure the support firmly to the concrete using appropriate heavy-duty expansion bolts or chemical anchors. Once the base is fixed, insert the wooden post into the support sleeve and secure it using wood screws or bolts through the pre-drilled holes in the side walls of the bracket.
What to consider before purchase
Ensure the diameter of your wooden post matches the 101 mm support size
Verify that the concrete surface is level and structurally sound
Check that you have the correct type of concrete anchors for your specific installation environment
Usage recommendations
Regularly inspect the connection points and the condition of the wooden post to ensure that the structure remains stable and free from moisture-related damage over the years.
