What is used to join two scaffold frames together one over the other?

In scaffold construction, joining two scaffold frames together one over the other is commonly done using pins. These pins are designed to secure the frames in place, ensuring stability and safety when the scaffold is used. The use of pins allows for quick assembly and disassembly, which is essential in scaffolding operations where mobility and efficiency are key.

While other methods of fastening exist, such as using bolts or brackets, pins are preferred for their ease of use and ability to provide sufficient support without complicating the assembly process. Pins are specially designed components that align with pre-drilled holes in the scaffold frames, making them user-friendly and effective in maintaining the structural integrity of the scaffold system.
