What is the maximum angle at which a spur should be set?

The maximum angle at which a spur should be set is 45 degrees. This angle is often considered optimal because it offers a suitable balance between stability and workability. A spur set at 45 degrees provides enough surface area to effectively distribute loads, while also ensuring that the structure is stable and secure. Additionally, this angle allows for efficient access and maneuverability, which is crucial in various construction scenarios.

Setting a spur at too steep of an angle can lead to instability and potential failure under load, while a flatter angle may compromise the effectiveness of the scaffolding system. Therefore, 45 degrees is a widely accepted standard in the industry to ensure safety and functionality in scaffolding practices.
