Pickets are driven in at what angle during setup?

• A. 10 Degrees
• B. 15 Degrees
• C. 25 Degrees
• D. 45 Degrees

Answer: (B)

The angle at which pickets are driven affects how well the anchor resists pullout when loaded. Driving the picket with a slight lean into the direction of the force creates a downward component that pressurizes the soil and uses friction and camming to keep the stake from sliding out. About 15 degrees is the sweet spot because it provides enough lean to enhance hold without making the stake prone to lever-out or bending. Driving closer to vertical (a smaller lean) reduces the camming effect, while leaning more steeply (larger angles like 25 or 45 degrees) can place more of the load along the stake and ground surface, increasing the chance of pullout or instability. So, around 15 degrees is the recommended setup.
