The Shaw Installation Kit Includes:

30 Spacers:
Spacers are 1/4" wide at their widest Point, so by placing two or more spacers together it is possible to adjust the amount of expansion space by simply adding another spacer. One spacer will provide 3/16" expansion space, Two spacers placed in opposition will make a 1/4" expansion space, three spacers have "serrated" edges that lock them into the correct position once a board is placed against them.

1 Rasp or Wood File:
In areas such as a doorjamb or cabinet kick base where planks cannot be angled to lock into place, use the rasp or wood file tool to remove (file down) the locking ridge from the bottom of the plank groove.
