Box sealing system DS 90 / 120 mm

The box sealing system DS 90 / 120 mm covers an additional range of applications in building fire protection. The increased diameter makes it possible to use a larger number of cables and electrical installation conduits and also greater diameters. With this system, it is also possible to mix the installation of conduits and cables. In addition, full population, as with the DS 90 / 74 mm, allows use of the system in all fields of building technology. Because no additional materials are used, non-destructive retrofitting is also possible. The tried-and-tested screw fixing permits clean, safe and secure installation.
  • Secure, visible, certified fire sealings
  • Seals wall feed-throughs
  • Automatic sealing of the joints and gaps between cables - no filling and smoothing
  • Non-destructive retrofitting
  • Also for mixed population of bundles of cables and conduits
  • For timber stud walls F30-F90 or EI30-EI90
