The Directional Wheel Locks by Ferno deliver a high-precision wheel tracking accessory engineered to optimize ambulance cot steering control during straight-line patient transport. Designed for intensive emergency medical service operations, these structural lock tabs clamp onto the caster housings to prevent unwanted wheel pivoting. The locking system forces the casters to track in a straight line, ensuring smooth guidance down tight hallways or ambulance ramps while allowing transport crews to quickly disengage the locks when full 360-degree swivel maneuverability is required.
