What angle range should Rescue 42 Struts be placed in?

• A. 15-30°
• B. 0-10°
• C. 90°
• D. 45-70°

Answer: (D)

Stabilizing a vehicle during extrication depends on getting the struts positioned so the load is carried in compression through the strut while the base remains broad and resistant to sliding. The 45-70 degree range provides the best balance between strength and stability: it lets the strut carry significant axial compression while also creating a horizontal component that helps wedge and brace the system against movement. If the angle is too shallow, the setup tends to slip and can’t resist lateral forces well. If the angle is too steep or vertical, the load path becomes less effective at countering tipping and shifting, increasing the risk of buckling or loss of stability. So, around 45-70 degrees is the practical range for maintaining a safe, stable support during extrication.
