Manta Ray® Earth Anchors

Manta Ray Earth Anchors MANTA RAY® percussion-driven earth anchors are driven, tipping-plate soil anchors used to resist tensile loads up to 20 tons. This simple, effective, and economical system has proven performance across civil construction and marine anchoring applications.

Easy to Install. Engineered to Last.

The MANTA RAY® Anchor System is a leader in driven anchoring technology. It combines fast installation with long-term durability. Anchors penetrate tough soils and even asphalt, yet are compact enough for tight, hard-to-reach areas using lightweight tools.

Patented Design. Asked for by Name.

The original percussion-driven earth anchor, MANTA RAY® is widely specified by engineers. Each anchor is a one-piece, galvanized ductile iron casting with a chiseled-tooth leading edge for penetration in a wide range of soils—from swamps to decomposed rock to asphalt. Models MR-SR to MR-4 install with the same high-grade drive steel set.

Frequently Asked Questions

How is capacity verified?

MANTA RAY® anchors are proof-loaded at lock-off using a Load Locker, providing immediate on-site verification of holding power.

Why choose MANTA RAY® over concrete deadmen?

Unlike concrete deadmen or heavy ballast, MANTA RAY® anchors require no excavation, no spoils, and no cure time. They install with compact tools, perform across soil types, and deliver instant, verifiable results, reducing labor, mobilization, and cleanup costs.

Where are MANTA RAY® anchors commonly specified?

They’re widely used for light to moderate tensile loads in civil and marine work—especially tight-access sites or projects prioritizing rapid installation with proof testing at lock-off.

Are MANTA RAY® anchors removable?

No. Once driven and proof-locked, MANTA RAY® anchors are not removable. If removability is required, consider CHANCE® helical anchors.

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.
