When do I need “3p high”?

“3p high” was developed to enable the use of a long-handle triangular screw. The screw joint is set higher up to provide enough space below for the tool’s lever strokes, allowing it to be opened and closed without being moved. This saves time, especially in urgent cases. The bollard’s small diameter means the clamping cones may jut out slightly. If in doubt, please contact us.
