Sleeves for all poles can be installed on crushed rock
or a concrete block. To allow for drainage, sleeves
should not be completely encased in concrete.
After pouring the concrete piers, allow them to fully cure.
The dimensions of the concrete piers shown here should
be considered the minimum requirement. The overall
dimensions of the concrete piers are to be determined by
the local contractor and should take into consideration the
local soil conditions, water table, and frost line.
Cast the u-bolts into concrete for the net anchor footings.
Use a 3/4" or 1" dowel, PVC pipe, etc. to span the hole of
the footing hang to ubolt over this to maintain its height.
Pull the dowel out after the concrete has cured.
For the four special footing add chain to the u-bolt.
