ANCHOR
RECOMMENDATIONS There are four types of
anchors that are most commonly used with our towers, screw in "Auger"
type anchors, hammer driven "duckbill" anchors, cast concrete anchors
and expansion bolts (for use only in solid rock). What anchor should be used depends
on the soil type that the anchors will be placed in. See the following table for
our suggestions.
