Introduce  the  wedge  head  in  the  gap  between  flanges  until  the  vertical  side  of  the  stop 
interacts the flange outer surface (Fig. 3a).  
 

(Fig.3а)

 

 
Make sure that the whole step surface is used.  

We strongly recommend to use two tools for spreading the gap between flanges that should 
be mounted at an angle of 180 degrees to each other (Fig.3b) 

Fig.3b

Introduce a safety unit into the gap and shift load on it after spreading flanges to desired 
depth or the maximal spreading value for the given step block (Fig. 4).

For further spreading of flanges introduce the wedge head into the gap between flanges and 
use the next step of the wedge head.
