Ringlock horizontal also plays a supporting role in scaffolding support. The shorter horizontal bar is used as the horizontal support for a plank or guardrail. Insert the plugs at both ends of the horizontal bar into their corresponding taper holes within the standard rosettes, then hammer them together tightly. It is easy to connect the horizontal bar to the vertical bar, thus creating a full ringlock system with a vertical bar and diagonal brace. The horizontal bar is also hot dip galvanized.
