## Summary description

The Koelner U-shaped post support (D-TC-816) is designed for secure installation of wooden posts into concrete. Featuring a durable 81x60x4 mm construction, this support provides stability and protection against ground moisture. Ideal for fences, pergolas, and garden structures, it ensures a reliable connection between the post and the foundation, facilitating professional-grade outdoor construction projects.

## Long description

The Koelner U-shaped post support for concreting is a robust structural component engineered to provide a secure and stable connection between wooden posts and concrete foundations. With dimensions of 81x60x4 mm, this support is specifically designed to anchor timber elements firmly while elevating them above the ground surface. By preventing direct contact with the soil, it effectively minimizes the risk of rot and moisture damage, significantly extending the service life of your wooden structures.
Advantages
This post support offers exceptional durability due to its high-quality steel construction and precise manufacturing. The U-shaped design ensures a snug fit for standard-sized posts, providing lateral stability and resistance against wind loads. Its installation process is straightforward, requiring the base to be embedded directly into wet concrete, which creates a permanent and reliable anchor point for various outdoor building projects.
Suitable for
Installation of wooden fence posts
Construction of garden pergolas and gazebos
Building carports and small wooden shelters
Securing timber supports for decking or garden structures
When it may not be suitable
This product is not intended for use in structures requiring high-load bearing capacity or complex architectural engineering, such as multi-story buildings. It is also not suitable for installation on already hardened concrete surfaces without specialized drilling and anchoring equipment, as it is designed specifically for being set into fresh concrete.
Key specifications
Type: U-shaped post support for concreting
Material thickness: 4 mm
Internal width: 81 mm
Side height: 60 mm
Application: Concrete embedding
How to use
To install the support, prepare the foundation hole according to your project requirements and fill it with fresh concrete. Insert the base of the U-shaped support into the wet concrete, ensuring it is perfectly level and aligned with your layout. Once the concrete has fully cured and hardened, place the wooden post into the U-shaped bracket and secure it using appropriate wood screws or bolts through the pre-drilled holes in the side plates.
What to consider before purchase
Verify the exact dimensions of your wooden posts to ensure they fit the 81 mm width.
Ensure the concrete foundation is deep enough to provide adequate stability for the intended structure.
Check local building codes for specific requirements regarding post-to-foundation connections.
Usage recommendations
For optimal longevity, ensure that the wooden post is treated with a wood preservative before installation and that the support is installed with proper drainage to prevent water accumulation around the base of the timber.
