Which of the following is NOT a type of coupler or clip used in scaffolding?

The option identified as the correct answer refers to a term that is not recognized as a standard type of coupler or clip used in scaffolding.

In scaffolding terminology, "90s," "swivel clips," and "beam clamps" are all recognized as types of connections that are essential for securing scaffolding components.

• "90s" refers to angle connectors that allow for the joining of two poles at a right angle. This is crucial in scaffolding for creating stable structures that can support the weight of the platform and various loads.

• "Swivel clips" are designed to connect two scaffold tubes at any angle, which is particularly useful in situations where flexibility in the arrangement is needed to accommodate complex structures.

• "Beam clamps" are specifically used to attach a scaffold frame to a beam, ensuring it is securely anchored and reducing the risk of instability.

In contrast, "climbing clips" do not represent a recognized category of scaffolding couplers or clips. While there might be techniques in specific industries or applications that involve climbing elements, the term itself does not denote a type of coupler used in traditional scaffolding setups. Understanding these definitions is critical for scaffolding safety and integrity when constructing and using scaffolds.
