Installation Guide
Note: Prior to positioning the last deck 
board, place the end clips on the inside of 
the rim joist, securing them with a single 
screw inserted perpendicular through each 
clip into the joist.
Note: Use a square edge board for a 
smooth deck board edge on the perimeter 
of the deck. This requires creating a groove 
on the inside edge for the Phantom GT 
fastener. For best results, a Freud model 
#56-112 or Bosch model #85610M, 1/4 in. 
slot-cutting bit can be used. 
After positioning the last deck board in 
place, secure the deck board by angling a 
screw through the clip and into the board at 
a 30˚- 45˚ angle. Ensure the screw inserts 
fully and pulls the board down (2). Space no 
more than 12 in. (30 cm) apart.
Note: When thickness of rim joist exceeds 
11/2 in. (4 cm), end clips should be secured 
to the outer edge of the joist.

How to nish the installation with 
end clips on the rim joist interior
Secure fasteners by driving the screw fully 
into joist. Continue installing and securing 
the fasteners in the center of each joist 
along the remainder of the deck board.
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 complete the deck. Use 
PhantomGT Butt Joint Hidden Fasteners 
where two boards butt together to ensure 
adequate end-to-end spacing.
