The SCHRAUBFREI posts are 239 centimeters long. Of this length, about 50 centimeters are provided for integration into a foundation and about 10 centimeters for covering over the foundation (earth or paving). This results in a maximum fence height of about 180 centimeters. This is the same for all models. The inserted boards always cover about 180 centimeters.
If you create a concrete base under the privacy fence, for example from commercially available deep curbs, which should be 8 centimeters wide like the posts, the total fence height can be increased to about 190 centimeters. You achieve this increase because the posts do not need to be so deep in the foundation, since the space between the ground surface and the lowest fence board is filled by the curb. Overall, the post and thus the fence can be higher.
In addition, post extensions are available from SCHRAUBFREI. With these 80 cm long extensions, which can be force-fitted over the lower ends of the posts and fixed with screws, a maximum increase of 30 centimeters can be realized. With this variant, too, a base should be provided under the privacy fence. The described type of construction is especially suitable in case of different height of the ground in front of and behind the fence.
