The tried-and-trusted V-TEC VM cable glands from OBO are the quickest and most convenient way to provide strain relief and tightness with cable glands on junction boxes and housings. The integrated sealing lip and the specialized OBO slat technology provide IP68 protection. DIN EN 62444 has been used to test strain relief and tightness. The threads of connection are metric. Once screwed in place, the installation is there forever, as the optimum thread adjustment with the right pitch ensures permanent resistance to shaking.
