Cable sealing system LS 90, conduit sealing system RS 90

Pipe and fire-retardant systems for safe closure of passages and entrances in fire-protection walls. The certified retardants are quick and easy to install and can even be superimposed on cables and pipes retrospectively (EI90). In addition, the cable sealing system can also be used as a wall outlet that enables the connection of electrical attachments.
  • Secure, visible, certified fire sealings
  • For wall feed-throughs and entries
  • Without filling and smoothing
  • Automatic sealing of the joints
  • For cables from Ø 5 - 15 mm
  • For conduits Ø 16 - 25 mm
  • For timber stud walls F30-F90 or EI30-EI90
