Hidden Fastening Installation for Paramount Grooved Edge
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: Fiberon recommends the use of a quality joist ashing to ensure optimal installation and reduce potential noise caused by the boards
moving against the joist. Products such as Grace Vycor Deck Protector, Tite Seal, or other comparable self-adhesive ashing products enable a
smooth and consistent contact surface between joists and Fiberon Decking. Paramount Decking offers lifetime limited warranty coverage. To
extend the life of the joists beneath the decking, we recommend using joist tape. Properly applied, joist tape has proven effective in protecting
joists against premature decay.
PHANTOM20EC INSTALLATION
1
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 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.

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 decking
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.
NOTE: Follow instructions for Tiger Claw hidden fasteners (pg. 13) to install the mid-deck area before the end boards.
