Koelner D-TU-71 Bolt-Down Post Support 71 mm

The Koelner D-TU-71 bolt-down post support is a professional-grade mounting solution engineered for the stable installation of wooden posts with a 71 mm diameter. Constructed from high-quality, durable steel, this base provides a reliable connection between timber elements and concrete foundations. Its design ensures that the wooden post is elevated from the ground, which significantly reduces the risk of moisture absorption and wood rot, thereby extending the lifespan of your garden structures.

Advantages

This post support offers exceptional structural integrity for various outdoor projects. The robust steel construction is resistant to mechanical stress and environmental factors, ensuring long-term stability for fences and pergolas. By utilizing a bolt-down mechanism, the support allows for precise alignment and secure anchoring to concrete surfaces. Furthermore, the design promotes air circulation around the base of the post, which is essential for maintaining the health of the timber over time.

• Installation of wooden fence posts
• Construction of garden pergolas and gazebos
• Building small wooden sheds or shelters
• Securing timber structures to concrete patios or foundations

How to use

To install the Koelner D-TU-71, first ensure that the concrete surface is level and clean. Position the post support in the desired location and mark the anchor holes on the concrete. Drill the holes according to the requirements of your chosen anchor bolts. Secure the base to the concrete using appropriate heavy-duty fasteners. Once the base is firmly attached, insert the 71 mm wooden post into the support and secure it using the provided side holes to ensure a tight, wobble-free fit.

What to consider before purchase

• Verify that your wooden posts measure exactly 71 mm in diameter.
• Ensure you have the correct type of anchor bolts suitable for your specific concrete foundation.
• Check that the installation site is level to prevent structural leaning.

Usage recommendations

Regularly inspect the connection points and the condition of the timber base to ensure long-term stability and to check for any signs of corrosion or wood degradation.
