Manta Ray anchors are driven into the earth in a low profile making easier to drive but when the drive steel is removed and the load locker pulls up on the anchor rod, the anchor will flip pulling on undisturbed cone of soil,  giving a better hold and less chance for long term creep.

An SGC 8' long drive steel kit is needed to install all Manta Ray Anchors with 1-1/8" or 1-1/4" hex head in either 4-1/4" or 6-1/4" chuck size. A 60# class or larger pavement breaker/jack hammer is recommended for installation.

The big unknown when installing earth anchors is the holding capacity of the soils. The LL-1 Load locker not only sets the anchor but also load tests the anchor to give you a reading as to quality of the soils and how much the anchor can hold.
