• Install provided CONCEALoc

screw at 45°
angle through the fastener and into the joist
while applying pressure on the fastener.
• Install one fastener and screw at each joist
location. See specific and additional require
ments for butt joints.
• Make sure fastener is in full contact with edge
of baord and the screw is holding the fastener
down tight to the deck board.
• Place the next board into position against the
fasteners. Slightly raise the outer edge of the
board being installed and slide it onto the
fastener until the board contacts the spacer tab.
When properly installed the inserted board should
be in contact with the bent-forward spacer tab at
the left end of the clip. To achieve this use wood
2 x4 as a beater board at least 24” in length and
use it as a tamping block to bring edge of deck
board into contact with spacer tab to ensure
proper spacing. Never strike the edge of decking
directly with hammer as damage will occur.
Always use beater board.
• Install fasteners as detailed below.
Note that the two clips on the right
are shifted approximately 1/4” to
the right of center on the joists. If
this is not done the spacer tab may
fall within the gap of the butt joist.
• The last board will need to have the outside edge
attached using the method described in Step #1.
It may be necessary to rip the last board to fit.
