The cable box used as means of fire-stop for cable penetrations in walls and ceilings was first introduced by W. Wichmann Sr. in 1985. Thanks to numerous developments today we offer one of the leading concepts of cable fire-stops in economical and technical terms.

Our EasyFoam cable boxes and our Easy Foam Stoppers offer a simple solution to the problems of smoke sealing and sound insulation excelling in very low maintenance cost. Cable boxes already installed may also be fitted with the EasyFoam stoppers.
