This is an example of slope- uneven concrete surface.

Flange plate and D-shape outside threaded bushes are adjustable into different lock positions on each corner to keep fence post in straight vertical position.

This eliminates problems with slope-uneven concrete surfaces. Max Slope 10°.

Adjustable flange plate is mounted on concrete surface with Blue-Tip SCREW-BOLTS  through D-shape outside threaded bushes.

Final fine adjustment is done by turning locknuts until fence post is in  correct vertical position.

 

In this project we decided to mount fence posts on concrete surface instead of  concreting fence post  into the ground beside the concrete area. This project was completed quicker, cheaper and cleaner. 

This product also eliminates time consuming cutting / drilling concrete.
