When mounting from the operator‘s side (type B) the plastic covers are supplied loose. Once the handle has been mounted the covers are pushed over the end of the handle tube and the foot until they snap into the end of the groove at the tube end.
Both mounting methods (type A and B) allow the mounting of a pair of handles in the opposite position. This method could be used on doors (double handle). Depending on the door thickness longer socket cap screws DIN 912 might be required.
