INSTALLATION INSTRUCTION
FOOTING INFORMATION
Total footing depth is 24” less the height of the surfacing
plus the height of the blocking material. If you are using
12” of surfacing the footing hole would need to be 12” plus
the height of the blocking material (refer to both the side
and front cutaway views to the right).
If the structure is installed on an unlevel grade you must
adjust the footing depth to accommodate the grade. For
instance, if the grade for this component is 1” higher than
the surface grade of the main post you must dig your
footing hole 1” deeper.
You must place the bottom of the support post on a suitable
flat blocking material to prevent it from sinking further into
the soil. We recommend you use a brick, block of wood or
several inches of gravel. The footing depth does not include
this blocking material since materials used often vary.
It is the owner/installers responsibility to check local
building codes and to comply with those codes. All footing
depths listed here are recommendations and local soil types
and frost lines may require a deeper and/or wider footing
depth. If that’s the case you must add more blocking
material to accommodate the deeper footing, as the post
length will still only be installed at the depth listed in this
instruction manual.
Assemble the entire unit before adding the concrete unless
instructed to do so in the individual component instruction
sections.
