  • its small size enables a space-saving mounting and simultaneously a high water flow
  • are suitable especially for enclosures with low protection degrees to deviate arising water
  • caused by special vertical openings the water is trooping up centrically around the drainage holes and runs-off directly by mounting of the lug on the deepest point of the enclosure
  • due to their type of construction,  any liquid can escape at any time but is prevented to irrupt from outside into the enclosure
