Which of the following is NOT a type of hanger?

Beam clamps are not classified as a type of hanger in the context of HVAC and sheet metal applications. Rather, beam clamps are used to attach or secure other components to a structural beam, providing a mounting point but not serving the primary function of supporting or suspending ducts, piping, or similar elements.

In HVAC installations, hangers have specific designs tailored for suspending various types of equipment or ductwork. Clutch or cable hangers, for example, are designed to provide adjustability and are typically used for lightweight applications, allowing for easy height adjustments. Tear drop or sling hangers are intended for supporting pipes or ductwork with a more secure grip and configuration, while trapeze hangers are often used to support multiple pipes or ducts in parallel, providing a robust framework for larger installations. Each of these hangers plays a crucial role in securing HVAC systems, ensuring proper alignment and stability, which is why they are recognized as distinct types of hangers in the field.
