Application
Fire preventing system made by a stainless steel structure which can be opened for an easier mounting, also after the installation of the pipe. On exposure to heat from a fire (at the temperature of 150°C) they rapidly expand inwards to squeeze the collapsing plastic pipe until the aperture is completely sealed. The collar provides a fire resistance EI 120 both wall and slab.

Advantages

Rapid installation thanks to the tab closure.
Seal against the passage of fumes, gases, flames and heat.
You may install the collar into the wall in case of not enough space.
