What is an easy trick when using right angle clamps?

The correct answer highlights the importance of proper orientation when using right angle clamps. Installing the clamps on the vertical post with the open side ready to hold the horizontal tube allows for a secure and stable connection between the two components. This configuration not only facilitates easier alignment of the horizontal tube but also ensures that the clamp effectively grips both the vertical post and the horizontal tube.

When the clamps are oriented correctly, the user can more confidently adjust and secure the structure, minimizing the risk of misalignment during assembly. This method enhances the overall efficiency of the scaffolding setup, making it crucial for achieving stable and safe working conditions.

The other approaches lack this practical orientation. For instance, installing clamps facing away could lead to difficulty in securing the horizontal tube, while pre-assembling clamps before applying them might not guarantee the correct alignment necessary for effective use. Using additional clamps may provide support but does not directly address the correct positioning, which is essential for the initial setup of the scaffold.
