Advantages offered by the Triangle Builder

  • The wedge section at the top is our proprietary stopper mechanism. Crossing the braces activates the lock mechanism. This prevents dropout caused by vibrations or other factors.
  • You can hook the safety belt on the handrail.
  • The double handrail does not require a middle handrail when a scaffold is placed. This reduces necessary materials.
  • In a large-scale construction site, the Triangle Builder significantly reduces working hours.
  • In the society where safety is valued above anything else, the Triangle Builder provides increased safety of workers.
