There are several ways to install the MSL casing system, depending on the local conditions. The trapezoid-profiled models FS 2001 and FS 2001 G, for example, can be erected as in the following photos 1-5. This version makes it easier to insert the spacer.

  After you have tipped the casing at a 90 degree angle, it should stand on the lower brackets without additional help (Then the reinforcement can be attached).
