Description: DUCKBILL anchors, a patented labor and time saving device, work like a toggle bolt in soil. DUCKBILLS are driven into the ground (with no holes, no digging and no concrete), providing a safe and environmentally sensitive installation. An upward pull on the anchor tendon rotates the DUCKBILL into a perpendicular inchesanchor lockinches position in undisturbed soil. The result: superb holding capacities. DUCKBILL anchor systems offer the most effective, lightweight and economical solutions to any anchoring application, large or small. The 138 is the largest of the DUCKBILL anchors. The anchor is cabled with a 5/16 inch (7.9mm) cable. This anchor is installed with a small jackhammer and a power drive steel required. Anchor holds 5,000 lbs. in normal soil. Anchor holding capacity will vary in different soils. Increased capacities can be expected in harder soil classes (numerically higher blow count classifications) and lower capacity can be expected in the softer soil classes (numerically lower blow count). Anchors are rated in an average (class 5) soil condition. The rating is meant to be a reference for anchor selection. Proof-loading is the only way to insure the exact capacity of each installation. Normal Soil is defined as follows: Most Common Soil Types: Dense Fine Sand, Very Hard Silts and Clays, Dense Clays, Sands, Gravel, Hard Silts and Clays.
