Envirograf's Intumescent sleeve with adhesive backing to protect top and bottom of metal consumer unit.

Metal consumer units pose a great risk of becoming live due to overheated loose cables touching the box, which also haven't been properly earthed. Placing our intumescent sleeve inside the unit therefore prevents overheating and spread of flame.

Envirograf's intumescent sleeve consists of a silicone cloth material. The liner becomes fitted to the top and bottom of the unit, protecting the cable entry.
