    Description
    Manta Ray Anchors are RUS approved, rugged and versatile driven plate anchors for all types of soil conditions. They can be installed in extremely tough soils such as caliche, decomposed rock, glacial till, and permafrost.

    Every anchor is proof tested during standard installation procedures for a verified tension load measurement.

    Manta Rays are driven into the ground using a jackhammer, not augured or torqued. No excavation is necessary. The anchors are driven with conventional hydraulic equipment.
