Manta Ray® Earth Anchors

 

Manta Ray Earth AnchorsManta Ray® percussion driven earth anchors are driven, tipping plate soil anchors used to resist tensile loads up to 20 tons. The simple, effective, and low-cost anchor system represents a major breakthrough in anchoring technology with a multitude of applications across the civil construction and marine anchoring markets.

Easy to Install. Engineered to Last.

The Manta Ray® Anchor System is the recognized industry leader in driven anchoring technology. The ease of installation, coupled with the durability of the anchor itself, makes the Manta Ray® an easy choice for installers. The Manta Ray® is strong enough to cut through tough soils and even asphalt, but compact enough to be installed in tight, hard-to-reach places with handheld equipment.

How to Install Manta Ray® Earth Anchors


Patented Design, Asked for by Name.

The Manta Ray® is the original percussion driven earth anchor, and it is specified by engineers on more projects than any other brand. Manta Ray® anchors are designed as a virtually indestructible one-piece cast anchor plate, made from galvanized ductile iron. The chiseled tooth leading edge provides improved installation in a variety of soil conditions, from swamps to decomposed rock, to asphalt. Models MR-SR to MR-4 can also be installed with the same drive steel set manufactured from high-grade metals.
