Wall Duct System

Wall Duct System

SMO wall duct system is produced with the same high standards of security and convenience as all KETTLER products are. Based on this, the casing pipe wall duct “Optidur SMO” is constructed with impact resistant plastics, special rubber seals, threaded rings and other high quality components.

SMO is also applicable to buildings without basement since the outer geometry of the casing pipe features all necessary characteristics to ensure extraction resistance and non-rotatability. Assembling aids may be used conveniently for immobilising SMO prior to backfilling of the annular space. Pourable as well as applicable filling material may be used..

Complete assembling system

The casing pipe may be complemented by the SMO centring disk to complete the wall penetration system. By use of a centring excentric, SMO can be immobilised prior to backfilling. For clean and secure application of filling material between wall and casing pipe, integrated filling-aids may be used

Optidur SMO is available in two sizes:

  • SMO-1 for medium pipe between 20 and 40 mm
  • SMO-2 for medium pipe between 40 and 63 mm
