Phantom Hidden Fastener Installation - Grooved Edge Decking
NOTE: To reduce appearance of gapping at end-to-end seams and to limit the movement of the deck board along the joists, we recommend using
two Cortex screws or stainless steel composite deck screws placed into the deck at the joist location closest to the mid-point of each deck board.
This helps ensure that the deck boards stay positioned and maintain proper gapping as the boards expand and contract with temperature changes.
NOTE: The use of hidden fasteners is not recommended for installations at elevations above 6,500 feet.

PhantomEC AND Phantom20EC INSTALLATION

Installing the rst end boards
□ Fiberon recommends starting on the outside of the deck and working toward
the house/wall. This way, if any boards needs cut down to t, the cut side
will be against the house/wall. However, if starting at the house/wall, secure
Fiberon PhantomEC (24 mm) or Phantom20EC (20 mm) end clips a minimum
of 1/4 in. (6.4 mm) from the wall with a single screw into the joist.
□ Space clips no greater than 12 in. (304.8 mm) apart.
□ Position the deck board into the end clip fasteners. It may be helpful
to angle the board slightly to fully seat it into the clips.
□ Check to ensure that the board is fully inserted into the clips.
NOTE: Follow instructions for PhantomGT (pg. 10) or Phantom universal fasteners (pg. 11) to install the mid-deck area before the end boards.

Installing the nal end boards
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 to create a smooth, nished
look along the perimeter of the deck.
□ 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. Space no more than 12 in. (304.8 mm)
apart. The last board can also be surface-fastened into place with composite
screws installed ush with the deck surface or with Cortex Hidden Fasteners.
NOTE: When thickness of rim joist exceeds 1-1/2 in. (38.1 mm),
end clips should be secured to the outer edge of the joist.
