Hidden Fastening Installation for Paramount Grooved Edge (continued)
 TIGER CLAW HIDDEN FASTENER INSTALLATION
1 
Preparing the grooved board edges
 □ After installing the rst end boards (pg 12), insert a Tiger Claw 
TC-G hidden fastener into the groove of the board, centering 
on joists. 
NOTE: Grooved boards are not intended to be used as 
perimeter boards unless installing fascia boards appropriately 
to cover the exposed grooves, or when the groove is against a 
wall or other hard structure.

Securing the fasteners
 □ Secure fasteners by driving the screw fully into the joist. 
Continue installing and securing the fasteners in the 
center of each joist along the remainder of the deck board.
 □ Center-pin the board at the centermost joist with two 
Cortex fasteners.
3 
Installing the remaining boards/rows
 □ Position the next deck board into the fasteners. It may 
be helpful to angle the board slightly to fully seat it 
into the fasteners.
 □ Repeat installing fasteners and positioning boards 
to cover the deck surface. See “Installing the nal 
end boards” (pg 12) for completing the deck.
4 
Installing butt joints
 □ Where two boards butt together, allow for adequate 
end-to-end board spacing and use a Tiger Claw line 
fastener and a Tiger Claw butt clip on the joist to 
secure board ends.
