The 138 Ductile Iron Duckbill is a hot dipped galvanized heavy duty anchor that can be driven with much more force than the Aluminum version.
A 40# class or larger pavement breaker/jack hammer is recommended for installation depending on soils.
The big unknown when installing earth anchors is the holding capacity of the soils. The LL-1or LL-2 Load locker not only sets the anchor but also tests the anchor at the same time to give you a confirmed load capability.
