  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 will 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.
