Roxtec H3+1 UG™ seal

Transit for cables entering via foundations.

The Roxtec H3+1 UG™ seal is ideal for power cables in trefoil formation entering via foundations together with a grounding cable. It works as a long-lasting barrier against flooding, gas, humidity and rodents. It is a four-part seal that is easy to install also in wet conditions and in environments with running water. The transit withstands extreme cable bending and has a +3mm tolerance towards the aperture as well as an indicator showing when a compressed seal is achieved. The seal can be installed into knock-out sleeves, conduits and core drilled holes.

  • Watertight
  • Rodent resistant
  • Quick and easy to install
  • Provides excellent cable retention
