INTERNAL SLIDING  DOORS 
MUST BE LOCKED  IN TRANSIT  

Very important to make sure ALL  your internal sliding doors  are clipped  into place 
before  travelling  as shown below

If you do Not clip these into place  the door will slam shut and  break the  brackets
internally on the door  ....  
Ci  will  definitely  Not cover this  under warranty  !!!!!
They never break with normal use
