There are two parts to the RaceDeck® locking system:

  1. The Female Loop 

  2. The Male Peg
 
All tiles on any given installation should ALWAYS HAVE THE FEMALE LOOPS GOING IN THE SAME DIRECTION. (illustration 1)
  
Illustration 1 (Correct Method)

CAUTION: If you inadvertently rotate a tile 90° it will snap into place (illustration 2) but you will not be able to complete the installation properly.

ASSEMBLY
Always begin the installation in one corner, pointing the female loops in the directions 
that additional tiles are to be added.  See animation below.
