Key Components:
-
Plate with Stop Button: This assembly features an anchor connected to a stainless steel cable, secured with a UV-protective plastic disc. After load-locking the anchor above the plate, the tie-down is terminated with a hand-crimping tool, ensuring a secure and reliable connection.
-
Wire Vise: The Wire Vise assembly boasts heat-treated nickel components plated with aluminum, designed to fit flush with the 1/8 in (3.2mm) stainless steel cable. Once attached, the Wire Vise permits movement in only one direction, firmly securing the plate to the mat, providing unparalleled stability.
-
MacLean Power Grip (MPG): The MPG Soil Stabilization anchor system from MacLean Power offers a guaranteed holding capacity in the field, ensuring that each anchor system performs as expected, regardless of the soil conditions.
-
Rods with Plates: MCP also provides robust assemblies for secure fastening in combination solutions and hard armoring. Utilizing 3/8″ and 1/2″ diameter rods, this solution offers enhanced security and adaptability for a variety of stabilization challenges.
Manta Ray and Stingray Earth Anchors are engineered as driven tipping plate soil anchors, meticulously designed to leverage soil strength for reacting to tensile loads. These innovative anchors are renowned for their exceptional performance in a wide range of applications. Manta Ray anchors can handle working loads of up to 20 kips, while Stingray anchors, the more robust of the two, can manage working loads of up to 50 kips, making them ideal for heavy-duty projects.
The installation process is both efficient and reliable. Once the anchor is driven to the required depth using a specialized driving tool known as drive steel, the tool is removed, and the anchor is ready for the next critical step: load locking. This process involves tipping the anchor and proof testing it using the Williams Anchor Locking Kit. As the anchor shifts from its edgewise-driving position, it rotates to present its bearing area to the soil, effectively engaging the anchor's full holding capacity. This crucial step, known as "load locking," not only ensures the anchor is securely set but also provides an immediate proof test of its performance, offering instant validation of the anchor's load-bearing capability.
Manta Ray and Stingray anchors offer many significant advantages:
- Fast, easy installation
- Immediate proof test results
- No grout required
- Inexpensive installation equipment
- Environmentally friendly
- No drilling required
- Superior holding capacity
- Anchors for a wide range of soils & applications
The simple, effective, and low-cost Manta Ray and Stingray anchor system represents a major breakthrough in anchoring technology, with a multitude of uses in the utility, civil engineering, and construction markets, including:
- Utility Poles

The Manta Ray and Stingray anchor systems offer a versatile range of anchoring solutions, with eight Manta Ray anchors and three Stingray anchors, each engineered to handle a spectrum of light to heavy-duty holding capacities. These anchors are designed to meet the rigorous demands of various applications, ensuring a perfect fit for every project, no matter the scale.
Displayed below are six distinct Manta Ray anchor heads, each showcasing the innovative design and engineering that goes into these reliable anchors. Crafted from galvanized ductile iron, these anchors are built to withstand the harshest conditions while maintaining superior strength and durability. The anchors are specifically designed to utilize solid steel rods as load-carrying members, ensuring that they deliver maximum stability and support.
All Manta Ray anchors, except for the MR-88 and M-68 models, can be easily driven into the ground using the specialized drive steel set, making installation quick and efficient. Once installed, these anchors can be tested to the desired holding capacity using the load locker, providing immediate confirmation that they are securely and effectively set.
Whether you're securing a light structure or a heavy-duty application, the Manta Ray and Stingray anchors provide the dependable performance you need, backed by the quality and precision engineering that defines these robust anchoring systems.
