A single change in direction of less than 90° is known as a(n)____________.

A single change in direction of less than 90° is correctly referred to as a kick. This terminology is commonly used in piping and raceway systems to describe a bend or turn that directs the flow at an angle sharper than a standard elbow but gentler than a right angle. It’s an important concept in design and installation, as using a kick can help to minimize the space requirements and reduce stress on the piping or conduit.

Other terms provided do have specific meanings in the context of raceways and piping. An elbow, for instance, typically denotes a sharp turn, usually at a 90° angle, while an offset refers to a configuration that changes the course of the raceway in a way that creates a parallel pathway to avoid an obstruction. A saddle generally refers to a fitting used to connect smaller pipes to a larger one or to support the raceway.

Understanding these distinctions is crucial for effective planning and execution in raceway installations, ensuring that systems are efficient and compliant with relevant standards.
