Frequently Asked Questions

How does Core-Loc differ from Accropode?+
Core-Loc features slender flukes that interlock more deeply than original Accropode I, achieving comparable or superior hydraulic stability with lower placement mass.
What is the required slope for Core-Loc?+
The recommended slope is 4H:3V (cot θ = 1.33). Slopes of 3H:2V (cot θ = 1.5) are also widely deployed in deeper water.
