• Place the next plank into position against the fasteners. 
Slightly raise the outer edge of the plank being installed 
and slide it onto the fastener until the plank contacts the 
spacer tab. When properly installed the inserted plank 
should be in contact with the bent-forward spacer tab at 
the left end of the clip. To achieve this use a scrap piece 
of decking at least 24” in length and use it as a tamping 
block to drive the plank further onto the clip and the 
screw will fully engage the plank to the spacer tab if not 
already in contact. Do not use a hammer or damage to 
the edge of the plank may occur.
• The last plank will need to have the outside edge 
attached using the method described in Step #1. It may 
be necessary to rip the last plank to fit.

not done the spacer tab may fall
